Anyone suffered from this, had ct scan abdomen and pelvic done last night, and while it went ok, after couple of goes to get the contrast flow properly with me being told to raise my arm while the nurse kept pinching the tube, after few seconds I had to put my arm by my side and proceeded, when I got home I had headache and nausea, so was drinking lots of water as was told it takes 24 hrs to flush through your system, today no headache but have dizziness when stand and a feeling of full ears( if that makes sense) so still drinking water hoping for this all to subside, the arm where cannula was put in was slightly swollen first thing this morning, but not looking quite so swollen now, wondering if anyone else had a reaction
