osteoarthritis
"I have never experienced such pain or debilitation in all of my life. It has been three weeks, and I am still limping. I cannot sit, stand, or walk for any length of time. Had I known this level of pain was a possible side effect, I would not have used the drug. This goes beyond the usual injection site redness, this goes into swelling of the knee joint, pain up and down the leg, as well as the leg is feverish.  If anyone ever asks me about this or any other type of injection using this formula, I will tell them to really make sure there aren't other options before risking this kind of pain."
