Common causes of side pain
Side pain can originate from musculoskeletal problems (muscle strain, rib injury, inflammation of chest wall), kidney conditions (stones, infections), gallbladder or liver disorders, gastrointestinal causes (gastritis, pancreatitis, intestinal issues), gynecological causes in people assigned female at birth, pulmonary or pleural conditions, and nerve-related skin problems such as shingles. The likely source depends on pain location, character, and other symptoms.
