Re: What does a cold sore feel like?
Even if it is a cold sore, I don't think that it should be any cause of alarm for you. The majority of the population suffer from them, 90% in fact, and so it is more likely than not for someone to have them eventually. I've had a cold sore approximately 10 times over the course of my entire life (I'm 28), the first one happening when I was probably 14 or so.
No one has ever been concerned over it, myself included. If that is what it is with you, it should go away shortly and who knows when, if ever, it will return. :-)
