Hi

I have been having stomach pain and nausea for 4 months now.  I have been treated fot a stomach ulcer but endoscope noted nothing apart from some sores in oesophagus.  Doctor has said and advised that i should preferably go for an urgent CT scan but thinks the hospital will only send me for an ultrasound.

This moning i received an appointment for an ultrasound for my abdomen.

From what i hear a CT scan is more accurate but obviously more expensive.  However i need to know for sure if I've got something or not.  

Should I phone the hospital and ask for a CT scan or just accept I have to have the lesser check.  Thing is if the ultrasound fails to see anything and i carry on with the same symptoms will they do a CT afterwards. 

Thanks for any advice.
