Help docs! my tongue broke out in enlarged taste buds. why?

Probably Vitamin B : Take some vitamin b complex , in particular Folic Acid and niacin. Wait about 3 to 7 days .If symptoms resolve , it was a vitamin deficiency.If they don't resolve the rinse with benedryl for 3 min 3 x's a day. If still no resolution go and seek a dentist highly trained in oral medicine.

Taste buds: Could be sensitivity to food, poor oral hygiene, inflammation from smoking, viral, bacterial, from medications plus lots of other things. Perhaps even normal circumvallate papillae in the back of your tongue that were always there and you just noticed them. See your dentist or physician for evaluation.
