they told me I had a hiatial hernia.?

Hello, I have had problems for the last year. I had a procedure where they looked down my throat and they told me I had a hiatial hernia. The symptoms am having are as follows. I had a massive attack the other day that convinced me it was a heart attack.(pain under ribs in middle) By the time I got to the hospital about 30 mins, it had passed, I opted to go see my family DR the next day. I was nauseated and did vomit a few times that night. The next day my Dr did an Ultra Sound on the G-bladder. It was normal, but my blood tests showed a urinary tract infection. I was put on prilosce, and an antibiotic. I have a Hida/cck scheduled tomorrow. I have not been able to eat much, the gas and the dizziness is crazy, also I have been constantly nauseated, and have a low grade fever with back pain(mild). I have right shoulder pain, that will not go away. Had the Dr check it a few months back and we chalked it out to playing the kids Wii. Also bloating So here I sit wondering. HELP.
