I am suffering from the same thing as well, I do with all my pregnancies....pregnancy induced carpal tunnel
I use a brace at night and somewhat during the day, it is affecting both arms, but mainly my right!!!
The only other thing that I am gonna try is going to the chiropractor, My cousin is mine and she insists that altho it will not get rid of the syndrome all together, it will definitely help....
Plus, I LOVE laying on her table with the hole cut out for my belly!!!!!!!!!!!!!!!
It should go away after birth, just hang in there. My hands fall asleep typing, driving, eating, sleeping you name it.
I usually just hang my hand off the side of the bed when it gets real bad...so not only are we limited on how we sleep, we have to hang limbs over the edge of the bed =)
GOOD LUCK
and COngrats on Twins,
I am prego with my third and final child, another boy =)
