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.
Research shows that lying down after eating can cause indigestion because your body wants to relax while your stomach is working to try and digest all the food consumed. If you feel tired, take a nice stroll after a meal to stay awake and promote digestion, or just sit in an upright position if tired.
