I've had carpal tunnel for years ( from my previous jobs). The tingling, pain, and numbness is common with this but never had the blue hands. However with DS#1 I did have the numb hands. It was so bad I couldn't brush my hair! Everytime I lifted my arms above my head ( to wash or brush my hair, reach for something, ect.)y hands would go numb. It was a circulation issue that had nothing to due with my carpal tunnel according to docs. I kept it until ds#1 was about 3 months old! With #2 it never came back. Talk to your doc. I don't know what they can do but its always best to ask. Good luck!
