I had a CT scan yesterday at park hospital and it was my first to experience it and I had that fuzzy contrast dye in me and I felt like i'd pee'd myself but I didnt anyway. I had to have it done because my left kidney has withered away I think its called atrophy and that's why they investigating it and i am only 34yrs old but the doctor did reassure me that it wasnt cancer and it was not life threatening too. I have got a renogram scan soon at the city hospital in nottingham on the 6th November.
