Home Laser Therapy and Pain Management – No Special Skills Needed

You don’t have to have any special skills to use a cold laser. Anyone can learn the special techniques and knowledge that I teach, which will give you better results and superior performance from your cold laser. I have available for you the world’s best FDA Cleared home use approved over the counter (OTC), multi-technology home use cold laser unit or device for personal and professional use. This therapeutic healing cold laser stands head and shoulders above other cold lasers and low level lasers in the field because it is designed with the home user in mind, as I will reveal to you shortly.

At home laser therapy is gaining greater popularity as many people are finally discovering that this amazing, life-enhancing technology actually exists and that it is easy to apply. Once you try it, it doesn’t take long to realize how well the body responds to the healing power of coherent laser light. Many of my customers ask me, “Why haven’t I heard about this technology until now?” The fact is, it’s been around for over 50 years. It has been a main stay in Asia and Europe from the beginning. In Canada it was originally embraced for use with animals, especially popular with the Equine community of show and race horses to improve performance and recovery with a 35+ year track record. In the US cold laser therapy was embraced for over 20 years in the horse racing and show horse community before the first lasers received FDA clearance for use on humans in 2002. Now it is a rapidly growing field of complimentary medicine. Lasers are used extensively in most branches of medicine and by nearly all major sports teams, athletes and trainers as a means of not only promoting rapid recovery from injuries, but also in the capacity of promoting superior performance.

Understanding How Laser Therapy Developed

Albert Einstein originally helped to bring LASER to fruition. Although he did not invent the laser his work laid the foundation for it to be created back in the 60’s. He said, 

We are essentially light beings. Your cells actually communicate with each-other via light energy. Every cell in the body that is weak, injured, toxic or sluggish in any way can greatly benefit from cold laser therapy. Why? Because stress, contraction, inflammation and lack of energy are the major causes of all dis-ease.

Most cold lasers can support reduction of inflammation and increased available cellular energy. However, some cold lasers are also ideally suited to treat acupoints for a do it yourself acupoint treatment with no needles, no pain and only takes seconds per point. Hundreds of Free Protocols provided from Discover Lasers LLC exclusively.

Home Use Laser Therapy – Choosing the Right Cold Laser

Many people are asking, “What is the best cold laser on the market?” Once you understand the range of differences between lasers and know what to look for, you will better understand why the Scalar Wave Lasers are preferred, even over other laser systems that cost much more such as Ercho…, Thor, and Q1000 and less expensive lasers such as ML830 or Sports Lasers that only use one wavelength. Most lasers only use red, infrared or sometimes both. We offer cold lasers with multiple wavelengths, probe style single point and cluster type lasers.

When challenges or problems in your life present themselves, it’s up to you to discover the opportunity. Everything happens for a reason. Shift happens when you learn to turn those Problems into Solutions.  For me the opportunity occurred when I discovered cold lasers back in 2002. The shift happened in my physical body as the laser unleashed a healing power within me that had been lying dormant for decades. My shattered and beaten hand and wrist was given a new life, my degenerative disc in my neck and restricted range of motion was alleviated and health was restored. Learning to find and maintain balance is a major key to navigating the many challenges that life can reveal. At home use cold laser therapy has given me something that I never dreamt possible over 17 years ago. I feel as if I have been given a new  lease on life. This experience has been precious beyond words. No more constant nagging pain, no more weak hand grip, no more, “I can’t do that, and that, and that….”

You Can Make Shift Happen

With the healing power of Cold Laser Therapy aka Low Level Laser Therapy or LLLT you are being given the opportunity to make shift happen on many levels. By tapping into your body’s innate knowledge and healing power, and supplying injured and aging cells with precious life giving energy and information; you may be able to turn back the ravages of time. You may alter the course of aging, wrinkles, skin conditions, injuries, and accidents. You can be a part of the solution. You can take back control of your condition and be part of the solution with natural, painless, non-invasive cold laser therapy, and without even leaving home if you make an investment in your own cold laser.


Opioids and NSAIDs vs Laser Therapy

Arthritis and Pain – How do you handle it without medications?

Arthritis and Pain – How do you handle it without medications?

Wouldn’t it be great to be able to wake up in the morning pain free, with no more aching back, no creaking knees, or restricted neck and shoulders?
If you suffer from aches and pains, you know the drudgery all too well. What’s it going to be like today? How are you going to get relief? Medication, anti-inflammatory herbs, restricted diet, special supplements, Corticosteroid shots, or in a worse case, maybe you are considering an operation.

When you are desperate, or in a hurry, non-steroidal anti-inflammatory drugs (NSAIDs) might be your treatment of choice? However, they don’t do anything to resolve the underlying source of your pain. Plus, both over-the-counter and prescription NSAIDs come with a long list of side effects such as: damaging the cartilage in your joints, or destroying your liver or Kidneys. So, instead of helping matters, NSAIDs are much more likely to make things worse.

There’s an important message here. It’s the difference between managing your pain and stopping it altogether. The treatments above manage it, but what you really want is to stop it.

Have you tried Class IV Laser Therapy?

More and more practitioners are getting wise to the many benefits that laser therapy can offer to their patients. We finally have a technology that is working to turn around chronic pain and injuries like nothing else ever has before. A natural, non-invasive therapy that actually repairs damaged tissues, rebuilds cartilage, banishes inflammation and pain and support the body to heal itself.

If you suffer from chronic pain, there’s a reason for it. In many cases, the root of the problem is caused by damaged cartilage. This is the flexible tissue between the joints of your bones and vertebrae. When wear and tear damages it, it can cause bone to grind directly on bone, resulting in osteoarthritis. Arthritis is the leading cause of hip and knee pain, back, hand and shoulder pain. While hip and knee replacements are now a medical option, in many cases they are not an ideal solution. Wouldn’t you prefer to keep what you already have and just make it work better? The down time and expense from operations, not to mention side effects or complications makes them less than ideal.

Additional sources of pain can come from weak or injured ligaments, which hold the bones in your joints together. Ligaments have a large number of nerve endings, which can result in pain if they are damaged or loose. You can also have tendons that have broken down and are failing to connect your muscles to your bones. When this degenerative process is permitted to continue, it can lead to pain, stiffness and swelling. Most tendon problems are a result of wear and tear from overuse or aging.

Fortunately, there’s an entirely natural form of treatment that can ease all of these problems. It can also help resolve pain from fibromyalgia, sports injuries, carpal tunnel, TMD, TMJ, Stenosis, spinal degeneration, subluxations, sciatica and more.

It’s called Class 4 Laser Therapy and it is FDA Cleared, super safe, effective and fast action. This form of therapy involves repeated Laser Therapy treatments directly to the joint, tendon, spine or painful tissue. This all-natural light based therapy stimulates the body to immediately start repairing on a cellular level. It triggers an inflammatory response that allows the body to heal itself on a cellular level.

Here’s how it works. Class 4 Laser Therapy triggers localized inflammation that increases the blood supply and flow of nutrients to the weakened area. The laser quickly deactivates 7 of the 9 enzymes that cause inflammation by up to 70%, thus creating a more favorable inner terrain for healing to take place. The laser delivers a flood or photons (energy packets) to the Mitochondria (power house) of the cells and they are able to immediately convert photons into Adenosine Triphosphate (ATP), which is the ideal fuel source for most cells of the body. This provokes a regenerative response that stimulates cell growth in the damaged tissue, allowing it to repair itself. Additionally, the laser stimulates a series of endorphin releases that are the natural opiates of the body that halt pain, elevate the mood and create a pleasant calming effect to body, mind and nerves.
The results that patients are getting from this type of treatment are extraordinary. Giving a new lease on life, turning back the clock, and defying the ravages of time and aging. In most cases, pain is banished, range of motion is restored, joints and spine begin to rebuild and regenerate naturally and life is restored to balance.

The success of Class 4 Laser Therapy has been so prevalent in Europe and Asia, that the FDA finally cleared it for use in the US. It took a long time, and most people don’t know about it yet, but that is changing rapidly as more practitioners, athletic trainers, podiatrists and chiropractors make it a regular part of pain management, sports injury recovery, Arthritis treatment and regenerative therapy here in the U.S.

It starts working immediately, without drugs or surgery. There’s literally no down time. It only takes a few Class 4 Laser Therapy sessions and patients see how this could give them a new lease on life. Even after just one treatment many patients begin to notice the reduction of pain, increased range of motion and find a restored sense of hope to naturally manage and recover from debilitating conditions.

Class IV Laser Therapy is the Future of Medicine

Class IV Laser Therapy is the Future of Medicine

Have you ever watched the TV series Star Trek and looked in amazement as the doctor pulled out a hand-held healing device and waved it like a magic wand over the effected area, causing it to heal immediately? That is how I feel when I use my therapeutic laser. Class IV Lasers are easy to use and extremely successful for treating countless ailments. Word is getting out and they are daily becoming more and more frequently used in clinics, hospitals, veterinarian clinics worldwide, podiatrist services, and chiropractic practices. Patients and therapists alike are benefiting from this incredibly helpful, non-invasive form of rapid laser healing with Class IV Laser Therapy. Practitioners are finding these safe, powerful lasers work quickly, enhance their overall treatments, improve patient results and referrals and increase revenues.

Healing with Class IV Lasers

Have you heard the buzz about using class iv lasers for healing countless ailments? These therapeutic lasers are being used by all kinds of therapist such as: Doctors, Dentists, Acupuncturists, DO’s, Oral Surgeons, Veterinarians, Chiropractors, and Plastic Surgeons. Additionally Therapeutic Lasers are being used by almost all major sports teams and Olympic athletes the world over. Athletic trainers are using these lasers to increaste athletic performance and rapidy sports related injures, thus saving coaches and sports teams from losing valuable players. Healing Lasers are being used in tens of thousands of Hospitals and private practices, and there are thousands of supportive clinical studies and white papers which reveal the effectiveness of Laser Therapy. Treatment with Laser Therapy is quickly becoming one of the fastest growing segments of alternative medicine and complimentary medicine.

Who Uses Class IV Laser Therapy?

Class IV Laser Therapy (C4LT) is used by Chiropractors, Medical Doctors, Osteopathic Doctors, Health Professionals, Podiatrists, Pain Management Clinics, Sports Therapists, Athletic Trainers, Physical Therapists, Estheticians, and Veterinarians. Therapists and practitioners have found that by providing Class IV Laser Therapy they can give their clients better results quicker, than with their conventional treatments.

Why Use Class IV Laser Therapy?

The physiological and chemical reactions in the body due to use of Laser Therapy are significant and varied. C4LT works to help relax muscles, alleviate pain (analgesic), reduce inflammation (anti-inflammatory) by deactivating 7 of the 9 enzymes that cause inflammation by up to 70%, reduce swelling (anti-edemic), boost the immune system by up to 150%, stimulate the release of endorphins (for pain relief and mood elevation or stabilization), increase microcirculation, repolarizes cell membranes (increased cell permeability), increases production of osteoblasts and fibroblasts (helpful in cases of weak or injured bones and atrophy), increase natural production of elastin and cartilage essential for rebuilding spine and joints, and most importantly – donates photonic energy to all cells it reaches, that need it. The significance of the varied actions of C4LT cannot be understated. The Mitochondria in your cells immediately converts phononic energy into readily usable “chemical” energy in the form of Adenosine Triphosphate (ATP). ATP is the primary fuel source for most cells in the body. Every cell in your body requires ATP, which gives it the energy it needs to function and perform at peak efficiency.

Clinical Benefits of Laser Therapy



*LASER THERAPY may produce the following benefits. Results can vary from person to person.

1. Anti-Inflammation:
Laser therapy has an anti-edemic effect as it causes vasodilation, but also because it activates the lymphatic drainage system (drains swollen areas). As a result, there is a reduction in swelling caused by bruising or inflammation.

2. Anti-Pain (Analgesic):
Laser therapy has a high beneficial effect on nerve cells which block pain transmitted by these cells to the brain and which decreases nerve sensitivity. Also, due to less inflammation, there is less edema and less pain.

3. Accelerated Tissue Repair and Cell Growth:
Photons of light from lasers penetrate deeply into tissue and accelerate cellular reproduction and growth. The laser light increases the energy available to the cell so that the cell can take on nutrients faster and get rid of waste products.

4. Improved Vascular Activity:
Laser light will significantly increase the formation of new capillaries in damaged tissue that speeds up the healing process, closes wounds quickly and reduces scar tissue.

5. Increased Metabolic Activity:
Laser therapy creates higher outputs of specific enzymes, greater oxygen and food particle loads for blood cells.

6. Trigger Points and Acupuncture Points:
Laser therapy stimulates muscle trigger points and acupuncture points on a non-invasive basis providing musculoskeletal pain relief.

7. Reduced Fibrous Tissue Formation:
Laser Therapy reduces the formation of scar tissue following tissue damage from cuts, scratches, burns or surgery.

8. Improved Nerve Function:
Slow recovery of nerve functions in damaged tissue can result in numbness and impaired limbs. Laser light will speed up the process of axonal regeneration, nerve cell reconnection, and increase the amplitude of action potentials to optimize muscle action.

9. Immunoregulation:
Laser light has a direct effect on immunity status by stimulation of immunoglobulins and lymphocytes. Laser Therapy is absorbed by chromophores (molecule enzymes) that react to laser light. The enzyme flavomono-nucleotide is activated and starts the production of ATP (adenosine-tri-phosphate), which is the major carrier of cell energy and the energy source for all chemical reactions in the cells.

10. Faster Wound Healing:
Laser light stimulates fibroblast development (fibroblasts are the building blocks of collagen, which is predominant in wound healing) in damaged tissue. Collagen is the essential protein required to replace old tissue or to repair tissue injuries.

*LASER THERAPY may produce the following benefits. Results can vary from person to person.

Frequently Asked Questions About Cold Laser Therapy

1. What is Cold Laser Therapy (CLT)?

CLT is the application of a cold laser over body, muscle, skin or acupoints to deliver photons (little energy packets) to sick, injured or compromised cells and tissues. Doing so may produce a natural healing response and a chain of beneficial actions in different systems throughout the body. Several cold lasers are now FDA cleared for Arthritis, temporary pain relief, increasing blood circulation and relaxing contracted tissues. Cold laser is thought to alleviate many issues that results due to inflammation because low level laser therapy is said to reduce 7 of the 9 enzymes that cause inflammation by up to 70%. Reduced inflammation may result in improved health. Cold lasers are designed to deliver photons in specific wavelengths and research and clinical studies have show to produce positive biological actions in the body such a delivering photons to cells. The Mitochondria inside of the cells is able to absorb the photons and convert them into Adenosine TriPhosphate or ATP for short. ATP is the primary fuel source of most cells in the body. Additionally, use of Cold Laser over specific acupoints on the body, hands and ears may stimulate the release of endorphins, which may support pain reduction and accelerated healing.

2. Is CLT painful?

Cold Laser Therapy is a painless procedure. You may feel a warm sensation or slight tingling because nerves are being stimulated, but this will subside shortly after your treatment is finished.

3. Does CLT involve any medication and is it safe?

Cold Laser Therapy is a completely safe, non-invasive, medication and drug-free procedure.

4. How long are CLT treatments?

Treatments can vary from seconds to minutes per point or location, depending upon the treatments protocol, type and power of the laser. Many people experience significant relief in 1-2 treatments. The length of treatment depends upon the number of things being treated, including the type of therapist doing the treatment and they type of laser being used. While some complete treatments will occur in 5-15 minutes with practitioners using the higher end, more powerful lasers. Other laser practitioners may spend 30-60 minutes treating the entire body and working on a variety of different systems such as blood, lymph, nervous, fat, chakra, organ and musculoskeletal systems.

5. What is Cold Laser Therapy generally used for?

This type of therapy may treat a wide variety of pain, spine and nerve issues including neurological conditions, pain syndromes such as sprains and strains, acute and chronic injuries, and speeds up wound healing and fractures. The additional ATP along with reduction in inflammation may support deep transformative healing. Additionally it may improve performance in sports and reduces athletic recovery in both human and animal patients.

6. Are there whole body benefits in addition to reducing pain?

Yes, whole body inflammation may be reduced overall with this therapy. When we complement Cold Laser Therapy with Chiropractic and/or massage care, it can help increase the rate, strength and quality of healing tissue. This therapy may also help regulate the immune system and stimulates nerve tissues to function optimally. In terms of healing, it has been shown to generate new, healthy cells within soft tissue to promote wound healing with less scarring.

7. Is this therapy FDA approved?

Cold Laser Therapy has been used successfully for the past 50 years in many countries throughout the world. Many Cold lasers are FDA approved or FDA Cleared with dozens of lasers starting as far back as 2002. CLT is used by US Olympic teams and most sports teams worldwide, to increase performance and recovery from accidents, injuries and overexertion.

8. Will it take long to experience results?

Most people experience results within their first visit or two. Results are almost immediately evident, but some people may need 3-8 sessions to feel significant improvement, especially if the issue has been chronic for some time. If you are experiencing a degenerative condition, see a Practitioner for professional advice. Some Chiropractors and Laser Practitioners may suggest scheduling an appointment from time to time for follow-up visits, for you to continue experiencing healing.

9. What are some of the health concerns that Cold Laser Therapy can treat?

Many specific conditions, both acute and whole body respond to cold laser. These may include, but are not limited to, rheumatoid arthritis, osteoarthritis, frozen shoulder, back pain, neck pain, fibromyalgia, headache, migraine, carpal tunnel, sinus concerns, deep bruising, tendon and ligament issues, and sciatica.

If you have any questions about whether a new or chronic health concern may respond to Cold Laser Therapy, please feel welcome to call us today to answer questions!

10. How long do the effects of the treatment last?

A single treatment can continue working in a persons body for up to 24 hours. Treatment length and frequency varies, depending upon the condition and type of laser used. An acute soft tissue injury or open wound may require multiple short treatments initially. The interval between treatments will lengthen as the issue improves. Chronic conditions typically take longer to treatment, with more treatments being the norm (up to 20), in order to support a change or transition out of old holding patterns, to allow deeper and more transformative healing to occur. The treatments have a cumulative effect, where each proceeding treatment builds on the success of the previous treatments to alleviate pain and support a rejuvenating, healing process.
