<s>[INST] I have clicking under left lower rib cage with either palpation of left upper quadrant or when slouched over. It occassionally almost feels like my rib cage is pinching my abdomen. No pain except for o ccassional moderate pain after eating. Ive been extra tored recently but attribute that to having an 8 month old. [/INST] mostly hiatal hernia with or without gastritis.an upper GI endoscopy can confirm that ..do you have reflux disorder ? </s>
