When my son was 17 he broke his collar bone, it was a complete fracture, the doctor put him in a brace allowing the bone to overlap and heal causing the collar bone to be an inch and a half shorter than the other. He is now 26 and for several years has complained about pain from head to toe on the side of his broken collar bone. He is constantly twisting and trying to adjust himself. He has been through several months of physical therapy with some marginal improvement, but not enough. Is it possible that his pain is from this shorter collar bone? He is thinking of having it rebroken and set to the appropriate lenght.Your response is greatly appreciated.
