I too was suffering from horrible nausea and abdominal pain. The doctor kept diagnosing me with a UTI. they would send my urine off for a.culture which never grew anything!! I was on 3 courses of antibiotics and the nausea never went away. After about 1 1/2 months of this I couldn't take the nausea anymore and went.to my local ER. There the doctor diagnosed me with PANCREATITUS. I spent a.week in the hospital on pain meds. I guess the moral of the story is don't give up on a diagnosis!! Take care!!
How long have these symptoms been going on? Have your symptoms been changing at all? Did your doctor run any lab work ups on you to tell if you have an underlying infection somewhere? I have all these symptoms off and on regularly they are part of my life and I always have Zofran and Fenergen on hand for nausea. Im sorry you are having this right now hopefully it is an easy fix :) Best of luck to you.
