Ladies I really need help. I do go to the doctors Monday but I am currently 27 weeks pregnant and severe pain to point I can barely walk its my left side around my hip definitely an organ but I do noy know . I really can't believe its stretching pain cause it is constant and extremely painful . I am on my feet 5 days a week 40 hours including lifting which seems to make it worse. It literally hurts to the point that I am very nervous.
