Re: Cold sores
I've never had a cold sore.
One of my exe's never had one either until we went to Italy. He thought the sunshine brought it on. It was really big and vile looking.
I remember one of these 'celeb' docs reckoned mixing coffee with a little water and putting that on helped if you had nothing else.
I've also heard dapping perfume on as soon as the tingle is felt helps too.
