Has anyone tried these? Do they work? I've just researched them and the theory sounds good - using woundcare technology, rather than anti-viral. Website here: http://www.compeed.co.uk/templates/declaration.jhtml As I sit here with a coldsore under my nose, the size of a small tomato, I am really hoping to hear good feedback here. Then I will rush out in the morning and buy some! Any experiences please?
