There seems to be many treatments out there. I surmise that they may all work for some and not others. That is why we need to try something else when not getting relief. I have sever arthritis in my back, shoulder, wrist, knee and who knows where else. A couple years ago I was taking 36 mis of hydromorph a day. Left me in a fog, very doped for sure. Canada legalized medical marihuana I tried it. Now understand that like many I tried smoking joints many years ago. I didn't like the high so I didn't use any for many years. Now I use marijuana oil and have great relief. No high. A real game changer. If you are in a state that allows medical cannibus it may be worth trying for you. Like everything else, it will work for some and not others, but it is worth trying.
