Hand/arm fall asleep when I sleep on my side.

Krista

I keep waking up and my whole arm is tingling and uncomfortable and my hand feels swollen. I have to shake it off and switch the side I am sleeping on...then it happens to the other side and wakes me up. I Also wake up with neck pain/ headache from same issue. Medicline pillows are so expensive, but my maternity pillow is not helping me. Any suggestions?
