I had Carpal Tunnel with Paige. And it was so annoying. I had it in my right wrist (luckily I am left handed). I found that keeping it elevated helped and occasionally rubbing it with some deep heat (but only when it got really bad). It didn't help that I slept on my right side most of the time and this made it worse because the blood flow was probably a bit restricted from the pressure of my weight on my shoulder when I layed down (is this making sense?). I found that laying on my back and my hand on my belly helped alot, but I couldn't sleep on my back past 20wks. It didn't completely go away until Paige was a few weeks old, but every case is different depending on the severity to start with. It ended up affecting my whole hand by the end of my pg.
