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.
A common cause of stomach ache is constipation: your body needs to move its bowels, but something is blocking or impeding this movement. You can ease constipation by eating or drinking fiber-rich items such as prunes, bran, or broccoli.
