I was just reading through this thread
http://www.myfitnesspal.com/topics/s...+cider+vinegar
on myfitnesspal message boards a little while back and I remembered that a lot of people taking apple cider vinegar (with the "mother" in it) had great improvement in their arthritis and joint pain. It couldn't hurt to try. The recommended dosage and how to take it is in the thread also.
Sorry you are hurting so bad, I really hope you get some relief soon
