What could cause numbness in hands and arms??

Ruptured or swollen disc in the spine, possibly the neck area , I had sergeory for this recently.

well my mom went completely numb on the right side of her body and experienced similar symptoms, she went to the doctor and they told her it was a carpal tunnel too, but when it got worse she went again and they gave her an mri and she discovered she had the early stages of multiple schlerosis.

so i would definitely go back and check that out because if that is what you are experiencing then you need to get on medication promptly.

It could be hypertension or maybe a pinched nerve in your neck , like I had awhile ago.

I really had it bad because it made my left arm numb and it also triggered a sort of panic attack. Make sure that you're using a good pillow (like a feather one) that properly supports your neck when you sleep. You can also try rolling up a towel and placing it under your neck for support.

The stress you went trough was not to little, some times when the neck and shoulders muscles get to tide you can get those sensation in your arms, try to get a Swedish massage and find some natural remedies for stress so you can enjoy your baby.

good look

It could be some residual problem from the epidural, or it could be heart, or it could be nerve damage of some other sort besides the epidural. You definitely need to keep going back or get another Dr. until you get this resolved.
