As a sufferer of occasional cold sores (thanks to a boyfriend 20-odd years ago who didn't care about kissing me whilst he had an active one

) I can heartily recommend Compeed cold sore patches!
Thanks to the aforementioned idiot (sorry boyfriend) I also ended up with a cold sore in one of my eyes - and believe me, you really don't want to go there in terms of the pain! (And I've had two children, lol - without pain relief!)
So I am ultra-careful these days - the patches are amazing. Not really to do with TA, but if I can help just one fellow sufferer through this thread then great!
