I thought that this was just a regular rubber band welt or something until almost exactly a year later my lip swelled up freaking huge, and formed a blister (no rubber band or any sort of damage this time, I wasn't even feeling ill or down or anything. I actually felt pretty good right before this which is unusual for me). It felt funny before I went to bed, but not tingly like I thought a cold sore should, so I didn't put anything on it but by morning time my lip was huge. It kept getting worse and worse until I finally shelled out the money for some Abreva. This is a picture of the first time it happened, before it got really bad. (sorry for up the nose!)
My questions are 1) This is a cold sore right? and 2) Do cold sores get activated from a damage? Or was the rubberband and the sore just really odd timing? 3) Its been about a month since the last one left, and there's a knot of scar tissue where the things were, it hurts to bite on it (No Twilight lip chewing for me anymore lol). Can I do anything about that?
