<s>[INST] I'm a 24 yr old woman, and for the past year I've had on-again, off-again pain in my left abdomen. Recently I've had a sharp pain in my lower left abdomen that lasted a couple hours. It's since been replaced by a persistent burning sensation in my upper left abdomen, stretching right and down in a right-angle fashion. [/INST] Hi,From history it seems that there might be having some chronic pelvic infection giving this problem.Consult Gynaec and get examined.Ultra sound of abdomen will give clear clue about your problem.Meanwhile take some NSAID medicine like Diclophenac medicine as needed.Ok and take care. </s>
