WELL let me say that even though I am a raging hypochondriac and about the throat in particular, that one sounds like no problem. In my 20's I had a white spot that would appear on my tonsils. Turns out they were infected and the white spots were little pus balls (I know, sounds gross), about as big as a BB. You might just find out that some antibiotics clear it right up. But since we're talking about your throat - where does it feel like you're having a hard time swallowing? Does it feel like a certain part of your throat is tight, or that the lump is in a certain location? Good luck!!
