I have just recently been back to my gp, because the pain was getting bad, and he informed me that the pain was due to lack of excercise, the muscles contracting and pulling on the joints!!(he did give me a prescription for pain killers, Im surprised he didn't send me off to see the psycologist as well, you know, its all in your head dear!!!!)he didn't even ask me if I excersised or how bad the pain was??, So has sent me off to the physio, whom I see tomorrow, shes a loverly lady, and Im sure will help me, and will tell me if she thinks its not what the doctor thinks it is. Sorry for venting
