What could that be possibly? No other symtom.
[|AI|]  Hi ! Possibly your father was feeling the pain of a mild attack of recurrent appendicitis off and on, and as it was left like that without any treatment, it has formed an appendicular mass with the momentum and intestines. This is an infected and inflamed mass which is thus painful to touch. The right management would be to report at an emergency room of a hospital, where they may admit him, and give intravenous antibiotics, IV fluids, and nil by mouth till it gets controlled and reduced. Sometimes, the response is not good enough, and emergency surgery might have to be performed with all its possible difficulties. Infrequently, the mass can be from other organs of the abdomen, like stomach, or retroperitoneal lymph nodes with super added infection, but all these can not be differentiated without clinical examination, and so I would advise you take him to a surgeon for an opinion on the management. Good luck.
