My husband had pulled or sprained his leg. He was in a lot of pain and i suggested to use this product although I had chose it for myself. He rubbed it on, no scent,coolness or warmth. He was uncertain if it had any results. then about 15-20 minutes later he said the pain was GONE. He was sad he didn't rub it on the top of his leg becasue it was hurting but all the other places he had rubbed it in the pain was gone. He was amazed. it did wear off after about 4 hours . I was impressed.
