I had two CT scans, one with contrast dye, the other with a special contrasting agent that did'n't contain the same dye(one without iodine as an ingredient). The first CT Scan was blamed for the end stage renal disease I now have, because it is known to be very hard on the kidneys. The second CT scan was done as though my kidneys were ailling, but they were already gone, forcing dialysis, which I'll have to deal with for the rest of my life.
This may or may not be your case, but do know that the contrast dye can cause kidney failure, and lead to diaysis, however, since you are alive to tell the story, there is no legal recourse.
I am not sure if that is a side effect of contrast dye or not? I have had it as well for a CT Scan with no adverse side effects but are you allergic?
Also, did they say what is causing these other problems for you?
