Sorry, but this product hurt so much! I had pretty mild knee pain and found this in our cupboards and rolled it on the inside of my knee a couple of hours before bed. I was woken up because both of the inside of my knees were on FIRE, as if I had been scalded! I figured it must have been this product, so I used soap and water, took two aspirin, and tried to get some rest. Never again!
Really helps relieve arthritis pain in my wrists and fingers. I don't think I would be able to continue playing guitar without it.
Used to great for my arthritic knee as well, but I finally got a knee replacement. No more pain!!
