I noticed at the back of my throat either side of the tonsils that I have a scattering of a lot of white spots and whitish areas. Looks a bit like thrush would I think anyway I noticed this about 3 weeks ago whilst I was taking a tablet called Zomel. I went to the doctor who gave me an antibiotic as he said I had a sinus infection and sounded nasal. I finished the antibiotic today and the white spots and white patches are still there ! Do I need to go back to doctors for more tablets? Anyone know what it is and why it hasn't cleared?
