After a botched chiropractic session, I ended up at the emergency room visit the next day with extreme rib pain. I was diagnosed with costochondritis (chest wall pain caused by inflammation of the joints between your ribs and breastbone. Symptoms include sharp, stabbing chest pain that is worse with movement). I was told to take NSAIDS (anti inflammatory) but there wasn't anything else they could do. I was told it would last approximately 6 weeks and they didn't lie. It was almost 6 weeks to the day before the pain finally subsided. I wish you the best and hope you find relief for your situation.
