Y ismy xiphoid process longer than normal and so tender to touch?

See below: Xiphoidalgia (xiphoidynia) is a relatively rare syndrome that is characterized by localized discomfort and tenderness over the xiphoid process of the sternum. Symptoms are often aggravated by eating a heavy meal or bending or twisting movements; they may also be associated with heavy work or a cough. Analgesics or a local injection may help.
