Once I get a reply from my latest email I will ring my GP. Consultant has told me that the already available monthly injections he is very reluctant to try because of the side effects so that rules that suggestion out. There is nothing more he can do for me so has discharged me on the proviso I have 6 monthly tests and any concern to be referred back to him.

I would have thought that they would contact the GP with your permission as a safeguard, not taking just your word for it. That could lead them to a sticky wicket.
