HiI had some stomach issues last week and visited my GP.

HiI had some stomach issues last week and visited my GP. From thinking back I put the issues down to either food poisining or eating greasy food. My bowels hadn't moved for a 3 days and the GP found my bowel had no movement, almost closed down.He prescribed motilium and nexazole with a warning that if I didn't feel much better the following day to come straight back in. He also ordered an Ultrasound of my abdomen. The tablets worked well and i felt much better.Last night I had some chicken coujons which were very greasy and woke in the early hours feeling unwell, not as bad as last week but unwell enough not to get back to sleep. I have been to the bathroom today and my bowels are working yet I have a pain in my stomagh, not crampy, more niggling. I have been drinking and eating a salad roll and rich tea biscuits and had no problem eating, but have little appetite.Just to be clear, when I was ill last week I had no apppetite and ate very little but did drink plenty. However I could feel what I did eat and drink sitting half way down my stomach for a long period.As I am feeling unwell again I have the Ultrasound scheduled for tomorrow. My question is: What exactly will they be looking for in the Ulltrasound? and finally how soon should I get the results?Sorry for the longwinded question.ThanksMark.
