I had carpal tunnel starting in one hand after my first pregnancy. The numbness was slight and progressed for over 20 years then went to the other hand. I did the splints which helped at night. Finally I had surgery and it worked! Carpal tunnel release surgery has come a long way and the key is not to wait until there is permanent nerve damage.
I could never have held a needle if I didn't have the surgery! You will know when you are ready.
