Yes, I am currently getting carpal tunnel (at 34 weeks) and have had it the last week or so. Same thing that it happens mostly at night, but I am left with a numb middle finger during the day. I mentioned it at my pregnancy yoga class last week to the midwife and she said it is likely to be carpal tunnel and that elevation can help somewhat, but I haven't found that much use. I looked it up in my pregnancy book and they suggested bandaging with a splint, which I haven't yet tried. I have found some positions more comfortable with it (eg. propping my arm up to cuddle around a pillow).
I have found it only to be bad in my right arm, while the left is fine, which I think is strange. Apparently it does go away not long after giving birth.
