I've had very sore hands and knucles for about 4 weeks now, my MW says its pregnancy-induced carpal tunnel syndrome. About two weeks ago my fingers on the right hand started getting numb and have stayed that way ever since... This is my biggest complaint - its awful to have tingley-numb fingers!
Anyway I've done some reading and it seems fairly common in pregnant women. Midwife suggested a hand-splint, which you can buy at a drugstore and is made specifically for carpal tunnel. Otherwise she says the only thing that will help is to deliver your baby!
