Reaction to CT Scan?

Hi all,  the last few days have not been fun (and to be honest, this is kind of gross), but figured I should share, since I have been sharing everything and it may help someone out there reading this.

As I posted the other day, I had a CT Scan with contrast dye of my abdomen and chest this past Friday (3-23-12).  As with previous scans with the lovely contrast material, that tastes so God awful, I came home feeling like I had the flu.  Basically the symptoms for me were being extremely tired, nauseated and a slight headache.  As per usual, I took a nap.  Unfortunately, unlike the previous times where I felt better when I woke up, this time I was not so lucky.  I woke up with heartburn.  Now, I've written about having heartburn before, but I can tell you, this was the absolute worst I have ever had.....the burning was constant and it was radiating all the way up into my throat.  I took Tums and Maalox, but nothing helped, plus remember I'm still taking a double dose of Prilosec every morning (40MG).  This severe heartburn kept me awake the entire night on Friday, and continued non-stop all through the weekend, until it finally subsided some on Sunday morning and left me with a side-effect, no one has seemed to have heard of before (why am I shocked?)  Anyways, all day Sunday my tongue felt as if it had been bitten or run over with a grater.  I tried to ignore it, used Chloraseptic Sore Throat spray to numb it, but it continued to get worse.  I looked at it in the mirror and was surprised to find it covered in red sores and a white, thick substance, which when I brushed my teeth and tried to scape it off, left me almost is tears and with a mouthful of blood.  I went to the doctor on Monday morning and they said it was thrush and now I'm taking Nystatin to clear it up. The family practice doctor I saw (not mine, but urgent care, since her office couldn't fit me into her schedule), was guessing and said he thought I had a reaction to the barium liquid they made be drink or to the dye (not sure if this is just hypersensitivity or an allergic reaction), and this caused the heartburn, which in turn, basically burned the inside of my mouth.   I see my gastro doctor on the 2nd and the pain med specialist on the 3rd, but in the mean time, I'm stuck with this....although they know what's going on.  Still waiting for the results of the CT scan.  It's hard to believe having a CT Scan could cause so much trouble, or just how much damage that acid can do....wonder what it did to my throat and my stomach lining?  Scary thoughts.
