I Am Having Stomach Bloating With Some Dull Aches And

I am having stomach bloating with some dull aches and an occasional twinge of pain on my left side. I saw my doctor Wed. and am having a ct scan at a local hospital on Thurs., 9/1. I was taking an antibiotic for a leg wound that was prescribed on 7/8 twice a day called doxycyclinehyclate. I then cut it back to once a day and stopped taking it completely on 8/7 when I started having stomach distress. The script for this prescription says that it can cause upset stomach and cramping, and my doctor thinks that this may be the cause of my problem, but I'm not so sure. So, that's why I'm getting a ct scan. I may have trouble drinking the liquid required for the contrast in the ct scan though as I have head trouble doing this before.
