Cold sores can form on the nose and around the lip and are incredibly irritating and itchy. The cause is the herpes simplex virus, and the best cure are antiviral creams, such as lysine, an amino acid. The creams can be applied directly to the painful sores, and if that’s not how you want to deal with the embarrassing problem, you can always opt for tablets. This helps to prevent new blisters from forming, and you should take between 500 and 1000mg each day to treat cold sores.
