Collar bone cracking and pain
For a while now everytime I go to do a push up my right collar bone starts to pop and crack and it hurts. I never thought about it that much but I ride horses so shoulders back is a very important thing so earlier today while sitting on my desk I went to roll my shoulders back and I felt that popping pain.
I put my hand over my right clavicle bone and I can feel it popping when I go to roll it back. With the popping comes pain.
There are two joints involving the clavicle. One at the sternum and the other at the tip of the shoulder; I presume you mean the latter, known as the acromioclavicular, or AC, joint.
The joint is subluxating when you place it under stress. It means that the ligaments stabilising the joint have been stretched or ruptured, usually by a fall on the outstretched arm. It's just one of the reasons that chiropractors take a serious dislike to falls off horses. Serious injury is all too common.
There's no easy solution; if it goes on clicking like that, it will become arthritic, and spurs often tear the supraspinatus tendon. The rule is, try not to do actions that make it click. That probably means no more pressups.
The ligaments can be surgically shortened but it's no simple procedure.
The joint will gradually stiffen as the cartilage degenerates but it won't necessarily be less painful.
My best advice to avoid those situations that make it click. I would recommend talking to the medical world to see what they suggest.
