I'm 14, Virgin, I have a lump in the inside lip, about the same size as a cherry, it appeared 2/3 days ago and has got bigger, I thought it was a pimple so I tried squeezing it but it has just swollen up, it's very painful! It's uncomfortable to sit down, walk, anything even touches it it's horribly painful, I don't know what it is but I need to get rid of it as it's just not nice having it?
