My xiphoid process is very tender to the touch. Been that way for a year or so. There has been no impact, gal bladder or any other issues! Whats wrong?

Costochondritis? Could just be an inflammatory process of unknown cause that is responsible for your symptoms. Ask your doctor if a course of anti-inflammatory medication is appropriate. It doesn't sound dangerous. Also, make sure to get a good physical exam from your doctor as well. Hope this helps!
