Hi, Has anyone else had oral thrush. After 3 double doses of antibiotics I have been left with oral thrush. I have been on 2 different courses of medication. Nystan and Fluconazole 50mg. twice a day. I was seen at the hospital, they took a lot of blood tests about 2 months ago but I have not heard anything. My mouth is so sore it is difficult to eat. I have tried several mouth washes but they don't help. Does anyone have any idea's please.
