<s>[INST] hi i have a pain under my rib cage on the left hand side, this is a dull pain most days, other times its so bad I cant move, they have checked out my gallbladder and liver, and tell me that i have polyps in my gallbladder and some cysts on my liver, and they have done an upper GI that showed no issues with my stomach.  I also have lots of gas   can you tell me what else I should be checking with [/INST] Hi, Welcome to Chat Doctor forum.  Your liver and gallbladder might be having cysts and polyps, but you didn't have pain there. So they can be looked after afterwards.  The reason for pain in the left rib cage may be the pain of the pancreas, spleen, stomach, colon, kidney, ureter, etc. I advise you to consult a surgeon for diagnosis and treatment.  Take more of green leafy vegetables, pulses, sprouts, and protein rich foods to hasten the recovery.  Wishing for a quick and complete recovery. Thank you. </s>
