there are white spots in the back of my tongue. they are causing bad breath and my tongue does not feel like before. it feels kind of numb... i also have a thyroid gland enlarged, my dictor took my blood for testing and sonogram of the land recently. i don't know the results yet. but i am really worried and freaking out. i am 19 years old male. i don't take any antibiotics or any kind of drugs. i don't have allergies either.
