i have a single bump in the back of my throat but i cannot see it it feels like a large pimple but doesnt hurt at all, also i just got over a sore throat, but that sore throat kinda turned into just a lightly scratchy throat with ocassional cough, and the odd thing is that durring the day the scratchy throat is gone for the most part, but back to my bump, i just relised it about 2 hrs ago after eating some chips, now i have tryed to drink it down what ever it is...but no luck....can someone tell me if this coud be bad at all...

i would like to know all the possibilities of this lump if possible.
