Aww thanks everyone
Just an update on this :
I went to see doc and she said that she will contact the hospital and ask about the options for me.
They could admit me as a day patient and heavily sedate me to do it, or maybe an ultra sound or another CT scan but she was reluctant to suggest that because I have had 4 or 5 in the last year and the radiation is 400 times that of an X-ray.
She doubted they would find anything wrong with the adrenal gland a year on and it was probably all ok but appreciated that I worried about it all.
So now I have to wait and see what they suggest next.
Thanks for all the support peeps.
