<s>[INST] I was at the Er last night with vomiting, bad pain in my right side I do have kidney stones but 2 mil. but onlt 2 stones, my worry is this everytime I try to eat I feel a tightening in my musel in my right side of stomach, and I get sick again and vomit, and the pain starts, and my back hurts like heck, and I m in tears. I don t want to be a pain in the butt and go back to the er, but am worried this maybe something more then kidney stones. only* they didn t send me home with any pain medicine because they said the 2 stones wouls pass by theirselves would* excuse my spelling doc. [/INST] HIWell come to HCMLooking to the history given here this could be renal colic but other differential diagnosis is also important, if the quality and nature of pain is different, Gastritis,(Acid peptic disease) gall bladder stone, liver pathology, these need to be ruled out, hope this information helps, take care. </s>
