I keep getting this numb tingling pain on my left upper back in my shoulder blade almost. I go to my doctor next week but anyone else have this problem? Should I call my doctor before my appointment? Oh and I'm like 28 weeks +5 days. I know you can get this pain in your back if a baby is hitting a nerve but it's so far up I just don't think it's that. Triggered ny if I sit up allot.
