Ball-and-socket joints are classified functionally as multiaxial joints because they can move bones along several axes. The muscles that surround the joints permit the humerus and femur to move away from the bodyâs midline (abduction), toward the bodyâs midline (adduction), forward (flexion), and backwards (extension).
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.
Any persistent stomach pains really do need to be evaluated by your doctor to make sure that they are not caused by a serious underlying problem. In particular, stabbing pains in the stomach after eating could be caused by an irritation of the stomach lining, known as gastritis, or by a stomach ulcer. Both of these conditions can be treated, generally with medications, and leaving them untreated puts you at risk for long term health consequences, such as intestinal bleeding.
