Ahhh My Tongue!!!!

My tongue has had these small little bumbs on it for almost two weeks now, they have gotten a little smaller but thats about it. They dont hurt or anything at all I went to my school nurse and she thought that I might have hand, foot, and mouth disease but I dont have a rash on my hands and feet. The bumps sort of look like raised taste buds but in the back there not really attached. Like if I rub them agains the top of my mouth I can feel them come up. I have no clue what it might be...

Thanks, :d
