Laser therapy is the application of light over injuries or lesions  to stimulate healing and give PAIN RELIEF, resolve inflammation, infection and stimulate the immune system.  It is therefore very useful for treating SPORTS INJURIES, NEURALGIA, DISC PROBLEMS AND PAIN GENERALLY.

It can also be used over acupuncture points instead of using needles.  Research has shown it to be useful in STOPPING SMOKING.

Laster therapy was developed in 1967 and there are many research papers.   The latest paper is THE LANCET - a landmark review on low level light therapy for NECK PAIN.
