I have been nauseous and dizzy the past couple days. Last night I had very bad stomach pain while eating. It went on for hours and my lower back hurt as well. I went to the doctor they did a urine test which came back normal but she ordered 2 ultrasounds for my stomach and I've had these 2 ultrasounds in the past. I'm getting nervous because my stomach felt like it was burning about an hour after I ate tonight, any info or comments would be really appreciated.
