My 10th rib on the left side sticks out further than my other ribs. I have no acute injury to reference. I just happened to notice a while back that sometimes when i breathed under load i would feel a pop in the area around this rib. It isn’t painful, it is just weird. Sometimes, when i do a large volume of pressing or kipping/butterfly movements, the area gets tender. The only thing I have read about that is similar is slipping rib syndrome. I have been to a few doctors and all the imaging comes back fine and they don’t see anything to worry about but it is strange to me that that one rib is a little further out than the others and something is possibly moving in there. Any ideas?
