If only they would tell you what it's about on the phone. It makes me angry they don't do that and they wonder why people get anxiety.
The appointment is with the GP and not with the hospital so it seems it might just be a routine follow up.
I know you are not that keen on your local practice so you'll want to get it over with.
He/she will probably read you the hospital notes and the fact they were sent to your GP and not direct to you seems positive. xx
