Tongue is white with ulcer on my tongue. no tonsils. white stuff on left side of throat it hurts and ear ache on that side. most likely viral right?

Tongue ulcer: It depends upon how long you have had the lesion. Does the whitish coating rub off? The fact that it is only on one side of your mouth is peculiar , but without more information, it would be best to see an oral surgeon to see which microorganism it is and how best to treat it.

Virus: Yes, in all likelihood you have an adeno virus infection that will last about ten days. Gargle several times a day and take ibuprofen.
