I wish I could comment not the drs. Unfortunately I live in Toronto... However you have a similar health system - not sure if this would work for you - but research. Get online. Talk to people in the know - look for a top notch ENT in your area then request a consult via your GP. The ENTs in my area are quacks for the most part, except for my back up guy who comes highly recommended from the head of the hospital here - I go to him for any immediate problems or small tags but my main guy is in Toronto. I can tell you when I was being treated here at PMH, my dr. there was training a young surgical ENT from Australia - my dr. trains international drs, and only picks one every 8 mos to teach them a technique he pioneered for treating oral cancer - so you have to be the best of the best to be chosen - anyway he left to go home to Australia - he was super nice, and very talented. I have NO idea where he ended up but he's in your country somewhere (not much help I know) his name is dr. Gundulac. Otherwise best of luck - and yes thrush can be painful and very resistant to treatment. Stay away from sugar as much as possible that may help. hugs.
