Thank you for your response. When I explained my problem to my OB, she gave me the number to an orthopaedist. The orthopaedist wasn't too specific, just said that I could get massages and take Tylenol, but that was my only options for treating the pain. And after I had the baby, if the pain persists, to come back for an MRI. And for now to try not to do, well basically - anything. I don't go to my OB again for another 5 weeks.
