Yes--be a pain in the butt. Take reinforcements. Nothing harmless hurts that much.

My mother, who had a history of polycystic kidney disease, went to the ER seven years ago in full kidney failure (a friend of ours came to pick her up for lunch out and drove her to the hospital, which was extremely lucky since the rest of the family was out of town and otherwise, nobody would have found her for several days. She would have died). The MD was short with her and told her to make an appointment with her regular doc that Monday and not waste his time. Mom and our friend raised a stink until they finally agreed to draw blood. As it turns out, her kidney values were the highest the hospital had ever seen.
