The pain in the lower right side of the rib cage is divided into different cases. In normal people, it occurs occasionally, mostly due to soft tissue injury, and the pain can be relieved by applying heat and recuperation. The right lower rib cage includes a relatively wide range of areas: the liver, gallbladder, kidneys, intestines, lungs, pleura, ribs, soft tissues, and nerves. Sometimes pain in the right lower rib cage belongs to diseases of the biliary system such as stones (antispasmodic and analgesic treatment, lithotripsy or lithotripsy to remove stones), cholecystitis (anti-inflammatory and analgesic treatment, requiring a light diet and no fatty foods), biliary ascariasis (antiparasitic and antispasmodic and analgesic treatment); kidney ureteral stones (anti-inflammatory, antispasmodic and analgesic treatment, lithotripsy or surgical treatment to remove stones); rarely colon perforation (surgical repair, anti-infection), liver abscess (anti-infection, surgical drainage, analgesia), liver tumor (surgical resection, analgesia). The pain in the lower right side of the rib cage can occur occasionally in everyone, but sometimes it needs to be treated first with pain relief and then with different treatments depending on each individual case.
