Clinical and experimental studies have provided evidence that lasers can increase nerve function, reduce the formation of wounds, increase the metabolic activity of neurons, and enhance myelin production (Bagis et al., 2002). The non-invasive nature of laser photo therapy enables treatment without surgical intervention. Low level laser therapy began to be used in the regeneration and functional recuperation process of peripheral nerves in the 1970s. 

Many doctors dismiss cold laser therapy as quackery, which is one of the reasons I have used it so much on myself, family, and friends before I used it on animals that can’t give me verbal feedback. One friend said it did little for her carpal tunnel pain, and went ahead and had surgery. Everyone else reported moderate to complete relief.  On myself, it sometimes takes 7-10 sessions for pain to be gone from an injury that has caused chronic pain.

Low Level laser therapy has been used for at least 30 years for pain reduction and tissue repair. There is strong evidence it works and new research is constantly being conducted to refine it. 

It works by blocking pain fibers and slowing the transmission of pain messages. This pain blockade allows for a reduction in inflammation and for tissue regeneration. 

In one way, LLLT acts like a local anesthetic and reduces pain signals going to the brain. After several treatments the nerves in the affected area become less irritable and pain lessens, allowing muscles to relax and healing to take place.

While some conditions are curable, some need ongoing maintenance and people need to return for a treatment every three months. While not everyone responds to the cold laser,  it is used to treat a variety of conditions including neck and back pain, acute and chronic pain, migraine, wounds, arthritic pain, fibromyalgia and lymphedema.
