I honestly don't know. Mine is in my leg. Yesterday we had to go to the ER. The ER doc swore he knew what RSD was, but then proceeded to *squeeze* my leg in the worst possible way. I seriously thought my sweet husband was going to punch him. Then the doc was like, oh, that hurts? Really?
I mean, I realize that if our specialists don't know much about the disease, ER docs know even less, but it's not THAT hard to listen to a patient. Really, it's not.
