Diclofenac
"I have had 6 surgeries on my right knee and now my left knee started bothering me I went to the doctor because I couldn't hardly bend it and walking was a joke. I have been on diclofenac for 2 days and i am totally surprised but I have no pain in either knee at this point, no side effects of this time. and I'm grateful that my doctor was aware enough to know to prescribe this for me"
