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.
Acid Reflux and Ulcers. If you have a burning sensation and pain in your chest area and rib cage after eating, it could be a sign that you have acid reflux (heartburn). Acid reflux occurs when stomach acid seeps into the esophagus causing you to feel a burning sensation and pain in your upper abdomen and sternum.
