I know that many people suffer from cold sores and they are a real pain. I can go for many months or even years without getting one but once they start it's not unusual to get multiple outbreaks one after another. It's not always possible to identify why they happen but I have been able to correlate a lack of cleanliness (touching my face with a dirty hand) with them and also excessive sunshine.
Recently, I had a long standing meeting set up with a very well reviewed girl and fortunately she had to cancel about a week before which is just as well because a couple of days later I got the tell-tale tingling sensation of an impending cold sore.
Those that don't suffer may not know but the genesis of a CS starts with a tingling sensation, usually on the lip, which turns into a clear blister within 24 hours, this then dries up and a scab forms which falls off within about 4 days. You would think that would be the end of it but a new scab forms that cracks and bleeds. The whole process takes exactly 2 weeks from start to finish and is horrible.
I have tried various remedy's from creams to patches but once the tingling starts nothing is going to stop the fortnight of irritation. One girl recommended an anti-viral tablet that you take at the first sign of one and I have tried this but I can't prove whether this actually works for me.
I have a belief that you have to have a predisposition to having them because I can't believe to there is a person on the planet who's body hasn't seen the virus. This theory is born out by the fact I had a partner of many decades who never got a CS despite contact with me when I definitely would have been infectious.
Of course, the outbreak of cold sores always coincides with touring girls that I want to see being available in my area.
