I never had cold sores before in my life, but, one of my sons suffers horribly with
them, so, I was familiar with
the what they're like. When they begin, I feel a tingling, usually on the right edge of my lower lip and within a few hours, several bumps will develop and progress to pustular bumps, they drain and ooze, get crusty and eventually go away. Periodically, I also get what is best described as chapped skin following the lip line of demarcation - the outer edges of your lips.
