Acromio-clavicular (AC) Joint check that out.. I to have a large knot on the top of my clavical bone at the end, away from my neck... seems like just rest ice advil are the keys to fix problem... I did read that it cant get much worse so .
I have experienced the same symptoms including an enlarged right clavicle bone at the sternum. Along with the clavicle enlargement, I have sharp pains in the muscles in my right chest that can run down my right arm and up through my neck. I have seen my doctor who diagnosed it as "extreme inflamation" caused from stressing those muscles or injuring it and then continuing to stress the muscles. I had an x-ray today to rule out any other abnormalities. She prescribed a high strength anti-inflammatory medication for five days and I am not suppose to lift, pull or carry heavy items. I will see what happens.
I was injured lifting 300bld medical beds and I know it caused damage to shoulder girdle as well as thrombosis of right jugular vain but the L&I Dr. thinks it OK and says I will never find the reason for swelling above both clavicle bones.. no one helped and it has been 1 1/2 years living with pressure at my throat and pain in arms, neck and back!!!!
I also have an enlarged end of the right side clavicle bone, suddenly came up the size of a squash ball in a couple of months. Now the whole right clavicle is enlarged but I haven't seen a doctor because it does not hurt to the touch and feels hard, like bone. My movement is now slightly restricted on the right side so I will be going to the doctor. However, someone told me it was because I am a tennis player and so use the muscles on that side more. Someone else told me it was because I have bad posture when sitting at my computer (I am on the computer for many hours per day). These ideas could be right but they don't explain the suddenness of it. I will keep an eye on this blog.
Wow I too have had this condition for several year and since I've lost weight since bariatric surgery I notice it protruding even more now. I had no idea there are so many people with this same condition and that no one seems to have had a concrete diagnosis so far. I think I'll finally make an appointment to specifically address this issue. I'm glad I came across this site because now I see that it could be something either not to worry about or something more serious. Good luck to everyone!
Beach Buddy, how are your symptoms doing now? Did u have any more difficulties after you took the meds?
Hello guys, Any updates ??
I did not read of any updates or conclusions. Anyone?
I have recently discovered the same protruding collarbone that everyone here has described. Headaches, neck/shoulder/arm pain. It protrudes more and gets red when I work out. I've had xrays - nothing broken or dislocated. Went to another dr and he glossed over it and said it was tension headaches. If anyone has found relief I'd be happy to hear about it. Going on 3 and half months now.
I read some postings that a few other people had this problem with enlarged clavicle. Can I have their results/experiences?
I too have just discovered a lump on my left clavicle bone. For maybe a month or so. It doesn't hurt. Dr. ordered me an ultrasound. Very strange that all these people have this also!
