What are painful white blisters on tongue?

Answer:
One possible reason could be due to something called, Oral Thrush. More info available at link here - http:/www.colgate.com/app/Colgate/US/OC/Information/OralHealthBasics/CommonConcerns/CankerSoresColdSoresAndInfections/ThrushCandidiasis.cvsp



Most likely caused by a virus, tiny and whitish they will last 3-5 days and become extremely sore and painful. They will often occur in sequential multiples of 3 to 4 per episode with a new one overlapping the older one almost immediately. The occurrence seems to be random in nature.
