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.
Food Poisoning. If you develop stomach pain after eating rice as an isolated instance, you may have food poisoning. Food poisoning will cause stomach pain within two to four hours after eating rice that is contaminated with an infectious organism. Food poisoning symptoms include severe stomach pain, excessive vomiting, nausea and diarrhea. In some cases, food poisoning can cause a low-grade fever.
