I have rheumatoid arthritis. I finally asked my doctor about my shoulder cuz my right clavicle and shoulder area always hurt and they stick out more. He just told me it was probably a tendon. But I call pish posh on that.
I believe this has to do with the body's overall posture and balance. If you regularly put more weight on one side of your body or favor one side excessively, your body structure will adapt to the kind of usage you put it through. A bad ankle can lead to a bad knee, which can alter the way you walk, making the rest of your body compensate. A bad lower back or sciatica will lead to improper balance because it sends pain signals down your legs. The same goes for the upper body. The way we lift things or even spasms in the neck and shoulder muscles can shift our structure in an unproportional way. If left unattended for extended periods of time, the body's posture can get stuck in those positions. See a chiropractor that knows how to properly align your neck and back. After your body is properly aligned, give it a few days before doing anything strenuous to let it settle in it's correct position. It might not put your collarbone back in place, but it will help prevent it from getting worse. I always tried to live an active and healthy lifestyle but due to several car and motorcycle accidents, it has been a bumpy road the past few years. However, I have learned that everything physical we do has a chain reaction oo the rest of our bodies. Take hot baths when possible to loosen up. Then spend a good 20 - 30 minutes to slowly stretch afterwards. This is the best advice I can give to my knowledge and hope it can help somebody else in need.
I have the same problem with my left collar bone .some times it's like a knife stabbing me . It's got bigger over the last year. When it first happened I couldn't sleep for the pain .drs told me it's the connecting tissue and just to take naproxine .mine is just getting worse .simple things like holding a plate can cause me lots of pain !! i asked for an X-ray to be told there was no point.its like talking to the wall some times .im fast loosing my trust in my drs .mine is so visableand sticks out loads !!!
You have described everything that I have experienced very much the same way. I started certain exercises, which has helped a lot; I'm going to try the book. Thank you for posting such enlightening information.
