Alright, here's my question. I was diagnosed with ADD a couple years ago, and in that time I've taken ritalin, adderall, and eventually settled with dexedrine. I take it as prescribed, and it works fine. Several months ago, I experienced some heavy-duty surgery on my shoulder/back. Most of the pain seems to have subsided, with the exception of some problems which will take require further surgery to fix... As I say, throughout most of the day, the pain that I experience at rest (that is, it's still painful to move my shoulder or if I exert myself too heavily, but when I'm not doing that) has diminished greatly, with the exception of my residual shoulder problems. I have noticed, however, a strong correlation between the administration of stimulants and the amount of pain I get in my shoulder/back. It's really quite incredible; sometimes it is strong enough that I can hardly walk, and the pain can last long enough to prevent any sleep at all. It is responsive to dose (higher = more pain) but seems to happen whenever I take my ADD meds. Has anyone else experienced this or have any good ideas?
