On my right side, the two bones below my collarbone protrude more than usual and are noticeably different to my left side. The protrusion is firm and is neither painful nor particularly sensitive. Do you have any idea what this might be?
The collarbone or clavicle is attached at one end to the sternum or breastbone and at the other end it is attached to a portion of the scapula or shoulder blade. If you press into the space under the collarbone you will feel the upper chest wall, which consists of the ribs, and the intercostal muscles, which are the muscles, located between the ribs. If you have ever seen a side of ribs in the butcher’s shop that will give you a good idea of what the human chest wall looks like. The two opposite sides of the chest wall are not symmetrical and identical. Sometimes a rib on one side of the chest may be more prominent than the other and this has absolutely no health implications whatsoever. It has probably always been like this but you have only noticed it recently.
