A member asked:

I was a week late for my period. i got it today. i have been having horrible upper left back pain/lower shoulder. could this be related to my period?

A doctor has provided 1 answer

Possibly: Anytime there is free fluid in the pelvis that irritates the lining of the body cavity(peritoneum) in sometimes goes up the paracolic gutters and gets under the diaphragm which can cause shoulder pain. It would be good to see a MD to clarify the source of your pain.
