Ball-and-socket joints are classified functionally as multiaxial joints because they can move bones along several axes.

Ulcer. A likely cause of stomach pain after eating is an ulcer. An ulcer is a deep, open sore in the stomach or intestines. The reason for stomach pain may be food or stomach acid that irritates the ulcer.

The most dangerous possibility is that you have stomach cancer.
