I have got developed some white patches on end of my tongue(right side) on 18.09.12. I am under medication from 26th Sept 2012. At Ist I was given Vitamin B & C for a week with Xylo Plus to apply locally. The next week Flagyl was added to previous prescription. Then I had been given Fluconalzole (150 Mg) tablets, Metrodinazole for 1 week . but there is no improvement. I have no pain or burning sensation while taking spicy food etc. But with a torch light I can see some tiny white protrusions over the right corner of tongue. Also I have vomiting sensation when my stomach is empty. What to do now?
