Let me preface this by saying as an Amazon customer since 1998, these "sponsored" reviews of the last few years are, IMO, one of the worst things to happen on Amazon since the beginning.I paid full price for a bottle of this in 07/15 and put it in my box of many similar products and promptly forgot about it until this Holiday week. I have the interesting life of one with Fibromyalgia, and early onset osteoarthritis in both of my hips, the left so far gone I'm temporarily in a wheelchair while arrangements are made for a replacement. I'm 45. Recently the narcotic pain patches and breakthrough med wasn't just not cutting it, an average day was me was sobbing uncontrollably in pain while my DH (& caretaker) watched helplessly. Even the recent steroid injection which normally should've given me some relief did nada. In desperation, my dear husband took the Nervex out of my "pain arsenal" and suggested giving it a try. Within five minutes of him rubbing the pinkish, odorless cream into my hip and thigh, my pain was gone. Seriously. I have no idea how it worked when more powerful products have failed, I'm just incredibly grateful that it is working, and 3x daily applications have given me a truly enjoyable, pain-free Christmas Eve. Thank You and please keep making this product!There has been no downside, or side effects to this product. But when the label says wash hands immediately, they aren't fooling around. I accidentally transferred a bit of the cream into my hand, then rubbed my eye. And before I could say G7 protesters with mace-melted contacts in their eyes, I, too, was learning water makes it worse, and to just wait out the the small amount of capsaicin in the product
