cold sores
"I've been getting cold sores for as long as I can remember. Usually triggered by stress, but sometimes for no reason at all. Over the years I've tried EVERYTHING, Zovirax..whatever was the new product on the market.
 
Denavir is the best topical ointment. But like everyone states, you must apply it as soon as possible - for me by the time I feel a slight tingle, it's too late. I was at work this time when I felt my lip tingle and literally ran home to get my Denavir. I suggest you carry the small tube in your wallet as I do now. I keep one at home, at work, and in my wallet - early application makes a huge difference in duration of cold sore. It's expensive - but worth it. One tip so as not to waste it - don't squeeze."
