Have you ever tried to do that in a rural setting??
This is a real issue, all surgeries near me are the same lot. Though its possible the receptionist at one of the other surgeries may let me make an appointment without pre-diagnosing my condition. Oddly she wants to know my ailments before giving me appointment (she’s leakier than a sieve and the best way of spreading information round the town), but the online system tells me to see a GP, when the asthma nurse will do. Sorry that turned into a rant.
But serious question, is it a cunning trick that asthma nurse tells you different and sometimes contradictory information each time you get dragged to go and see them? And is it possible to get out of going to see them every year? I can put a peak flow off the scale, have been using an inhaler for 25 yrs and am not about to forget how it works and start putting up my arse or anything, and if my asthma got bad, I promise, I would go to the doctor, myself, spontaneously.
