Go to Amazon.com and put in cold laser device therapy and you will see them I have 2 different ones, one was $329. and the other was $129. (prime free shipping) I put my feet on it for 10 minutes at high power. It also work for a number of things like arthritis etc. One man was going to a chiropractor and spending $50 3 times a week for the same treatment, he bought one and thanked me for telling him about how to get his own, it is red light therapy by laser. Good luck, Mary
