My girlfriend has been experiencing sharp, throbbing pain in her lower right back around her ribcage for the last two days. This pain radiates to her stomach, causing nausea. The pain isn’t constant, it’s sporadic. She feels fine when the pain isn’t occurring. Lying down versus sitting up seems to make no difference. This pain is something she hasn’t experienced before and she’s not pregnant. It’s not as bad today as it was yesterday. She just started P90-X and Piloxing workout programs prior to this pain, so there may be a correlation there. Neither of us have money for a visit to the doctor, and we have no medical insurance either. Any helpful insight or advice is much appreciated.
