Loyola Hospital is in Maywood IL, on the western side of Chicago. Bill has a great idea referring you to Loyola.
Another thought is Mayo in Rochester, MN. I assume when you said Madison you meant University of Madison Hosptial., Wisconsin ?
I agree, your Dr. saying you did not need something for the nausea was out of line. Nausea is a subjective phenomenon and not something the Dr. can see so IMHO he should believe you when you say you need something for the nausea.
Hope you can get a second opinion soon.
