about three to four weeks ago i noticed a tiny white bump near the tip of my tongue. It almost looked like a pimple. i picked at it until it "popped." then the next day, more appeared. and now one has appeared on the top of my tongue. they are irritating, and when touched, they hurt a little. I don't know what to do, because i have no health insurance or money for health insurance. I've looked through a million pages but i just want to figure out what it is :(
