I’ve been coughing for 3 weeks now, the other day I woke up with severe rib or right flank pain when walking, coughing, exerting myself. So I went to urgent care because it was Friday afternoon and my doctors office never returned my call from a voicemail I left. They did an X-ray and found nothing wrong so they diagnosed me with costochondritis. I’ve had it before and it felt nothing like this. I have a sharp stabbing pain anytime I move. It hurts so bad I can’t even cough to remove mucus. I know I have no broken bones or injuries but could it be my appendix or gallbladder? It’s on the right side near my bottom ribs. It starts in the back and radiates to the front. I have no chest or sternum pain. It hurts in that one area. It’s not getting better either. I’ve rested, and taken meds and nothing. It’s staying the same. Anyone had costochondritis and felt this way or maybe another condition?
