My husband was in a car accident 6 yrs ago, of and on since he experience chronic left flank pain and his left side bulges out. He has seen a number of back drs, neuros, ers, gps all say it's muscle and he has to deal with it. 2 days ago we saw a new ortho dr I met at the hospital I work at, he very concerned, says not his back, pain is too deep. Also says if muscle it would heal in 6-8 weeks, not 6 years. This pain is now the worst it's ever been and isn't subsiding. Ortho doc is order CT Scan and then go from there. Any ideas of what this might be?
