So I’ve had previous back injuries I’m a nurse and I’ve done this three previous times.. I’ve managed to get another back injury at work while I’m 34 wks pregnant. I’m wondering if I should call my OB.. I would usually just go to an urgent care and get muscle relaxers and some type of pain reliever but I know I most likely can’t take anything other then Tylenol. I’ve been taking Tylenol and it’s not helping the pain at all. At this point I can barely walk and I can I’m supposed to go back to work tomorrow. Does this type of injury warrant a call to my OB??
