I was diagnosed with Graves nearly three years ago, had RAI last August and am now severely hypo. I've been seeing the same Endo but not happy with him and there is another Endo at the same clinic I go too. I want to ask to see the other Endo on my next appointment in Feb and not sure of the best way to go about it. Should I ring up before or can I just ask on the day? I know I have the right to see the Consultant rather than a Registrar but wasn't sure of the procedure.
