Hi Gotoeden,
First I agree with Diandra, you should be under a Pain Consultant.
Many of us on here, myself included, are dealing with the pains of multiple serious conditions or injuries - or both. You will always find a sympathetic ear and the likelihood is someone will have had similar experiences as yourself.
Among my problems I have severe Neurological Hypersensitivity and arthritis in my hands, knees and right elbow. For the arthritis I take 60mg Arcoxia, a cox-2 inhibitor as the cox-1s are far less effective. It reduces the swelling and inflammation by 50-60%.
Anything you think I can help with, just yell,

Dave.
