When i look at my tongue it is covered in a white/yellow coat? i have lumps the same colour of my tongue that seem to go all the way into my throat?

Oral thrush?: You may have a yeast infection in the mouth - oral thrush but that needs to be differentiated from other things including normal coating from food. Especially if you are generally healthy and not at risk for poor immune system. I will recommend getting a check up with your doctor, not only to diagnose and treat the mouth condition but for proper preventive care.
