Question

Why is my collar bone raised above my shoulder?

Answer

There are many things that can cause deformity of the clavicle/shoulder, most of which can be determined with a physical examination, x-rays, and possibly laboratory work. So it is important to speak with your primary care physician. Some of the possibilities include healing fracture, acromio-clavicular separation, infection, tumor, or congenital variation. In the absence of known trauma, it is unlikely that you have a fracture (broken bone), but the only way to know for sure would be with an x-ray. Similarly, acromio-clavicular separations (damage to the ligaments that hold the clavicle in position in relation to the scapula/shoulder) are generally the result of a traumatic injury, but can only be ruled out definitively with an x-ray. Infection of the acromio-clavicular joint or a superficial infection can lead to changes in the contours of your shoulder. Typically an infection would be associated with other changes such as redness of the skin, tenderness to the touch, and possibly systemic symptoms. Tumors can also cause changes in the contour of the shoulder. If it has been present for "as long as I can remember", it may just be a normal anatomic variation that occurred during development (most people are asymmetric in some way). The potential for a more concerning process such as infection or tumor is the primary reason why being evaluated in person is a good idea. In addition, not only will your primary care physician or orthopedic surgeon be able to diagnose the problem, but they will be able to refer you for appropriate treatment and hopefully get you to the point that you are no longer symptomatic.
