The point on air con is a very good one, for the last 2 days I have been sat directly under an air con vent in our training room in Sale, at about 11:30 this morning I started to get a cold sore, could feel the tingle and now it's like a second head!
I very very rarely get cold sores and have had no contact with anyone who could have passed it on, I blame the air con unit, just hope it clears up soon, it's killing!
