I used this product when it was just being tested before because I had knee arthroscopy done on my knees .. it seemed to work, but I didn’t believe it. I stopped after running out of it, and my pain returned. I ordered it again and have been using it for about a week, and amazingly my knees feel better again. I also have been developing hip pain from compensating for my knee issues and have used it there, which also feels much better. I am amazed at the results and will continue to use Conolidine Topical. Thank you for such a great product.
