DDCC - Just wanted to say that I had this with my last pregnancy! I guess some women develop it during pregnancy, and it typically goes away right after the birth. Mine did, at least. Hope it gets better for you! I ended up having to wear a wrist thingee (darn it, pregnancy brain, can't think of the name - not a sling, a...?) Anyway, I got it at target, and it helped to wear it at night.
