Hello, I have had to cold sores in the past on my lower right lip. They where very small and after about a 7-10 day they where gone( I only had 2 in my life). Its been more than 5 years and I have a small red bump above my lip (not on the line) and it began with a little itching.( my skin get dry) when I notice the bump I put lysine cream on it and took a lysine pill. the next day it was still red, no pus or anything. I took a couple of Lysine pills and now I am on day 6, it is just about gone but it never got fluid fill or burst open, it was just there.
