Your right collarbone might appear bigger for a few reasons, most commonly due to injury or how a previous fracture has healed. Other, less common, causes include inflammation or even bone tumors.
Here's a breakdown of potential causes:
-
Trauma/Fracture: This is the most likely reason. A previous fracture, even one you might not remember clearly (especially in childhood), could have healed improperly, resulting in a bony prominence or enlargement. The swelling might be related to a recent injury as well.
-
Non-Union Healing: If a collarbone fracture doesn't heal correctly, it can lead to non-union, where the bone fragments don't fuse together properly. This can result in a noticeable lump or enlarged area around the fracture site.
-
Inflammation: Inflammation of the bone or surrounding tissues (e.g., due to arthritis or infection, although this is less common in the clavicle) can cause swelling and the perception of a larger collarbone.
-
Bone Tumors: While rare (accounting for a small percentage of all bone tumors), a bone tumor on the clavicle could cause it to appear larger.
What to Do:
It is important to see a doctor for an accurate diagnosis. They will likely:
- Physically examine your collarbone and surrounding area.
- Ask about your medical history, including any past injuries.
- Order imaging tests, such as X-rays, to visualize the bone and surrounding tissues. In some cases, an MRI or CT scan may be necessary.
Based on the diagnosis, your doctor can recommend the appropriate treatment, which may include pain management, physical therapy, or, in rare cases, surgery.
