@Elle: I have the same issue for years now..primarily on the right side, but it will also migrate to the left side..but when it does the urge OTC rack on the right side disappears. So the constant and increasingly maddening urge to crack only happens on one side at a time. I might only have a day of relief but then the whole things starts up again out of nowhere. There are people who post here who seem to enjoy the sensation. I find it depressing and disruptive, and frustrating that I haven't been able to find any answers to this. I am healty, have been tested for lupus, rheumatoid, and lymes…I had lymes over 15 years ago, and was treated..so I don't know if this is connected somehow. I tested negative for the other conditions. I think I eat healthy, but now am looking into supplements. Glucosamine produced no results for me. I exercise regularly and do yoga, but nothing seems to alleviate this. It's not painful, it just maddening because as soon as I crack, the urge to do it again is right back.mthis goes on from morning until night, and I find it hard to sleep because I can't get comfortable. I came and sounds like other people experience what I do, so I guess it's good to know I'm not the only one. I will have to try yoga
