I recently developed several (10-15) red bumps on the back third of my tongue. No, they are not normal taste buds, they are raised and larger than normal. So much so that when I swollow they irritate my throat. They are absolutely painless but I am concerned because now there is one on the roof of my mouth towards the back. Any suggestions? I was recently on a two - three week drinking binge and wasn't eating very healthy and smoking about a pack a night (not normal for me)... is this a result? Should I visit a doctor or give it some more time?
