What Causes Fleshy Bump At The Back Of Throat?

Hi, I noticed the other night after eating ice cream that a small fleshy bump appeared at the back of my throat. IT seems like it goes away and comes back. Over the last few days. I ve had a sore ear and headache off and on for about a week and now my throat hurts as well. I m starting to panic and I keep googling which is making it even worse. I ve convinced myself it s either throat warts or a tumour.
