The GP seems very unconvinced by my thrush diagnosis (to be fair it's the first time i think i've had thrush so could be wrong).
He keeps talking about 'congestion' and that pumping would solve the problem 
So, after one 10day course of fluconazole and things starting to improve, things have been getting worse again. Back today & he has prescribed me another 10 day course of 100mg at my request. But wants to send off a sample to test for everything/anything. If thrush doesn't show up he wants me to stop taking the fluc. (he said it would show up if i have it, but some sites say that's not true).
