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.
