I am a dirt bike rider and ride some technical terrain at times for hours, needless to say it takes a toll on this 53 year old body. I had moderate pain both hips from rigorous riding recently so I wanted to see if light therapy could provide some relief, 25 minutes on each hip at 2 different frequencies did the trick. I felt immediate relief and the process is totally painless. I recommend light therapy to anyone needing a quicker healing process. Schelle Lyon is professional and one of the sweetest persons you could meet. Please look into this technology because it works, it did for me!
