According to me a cold laser is a non-surgical treatment tool used by a licensed physician to help relieve knee pain caused from a knee injury, degeneration, arthritis knee pain, tendonitis of the knee. Individuals who suffer from chronic knee pain can benefit tremendously from treatments. The therapy is unique in that it enables patients to experience knee pain relief without knee surgery, medications or knee injections. Unlike pain medications and knee injections cold laser therapy treatments are considered non-invasive,do not cause any harmful side effects, and are completely painless.
