How can I treat a cold sore is already on the plate?
I had to come all night and I felt nothing tingling and then this morning I woke to find two small blisters on the lips. What can I use this? I had a hard time this month so I think that's why we came. It happened in the same place every two years! Darn things.
You could use Abreva and Carmex … good luck .. I receive from time to time and they hurt. Mine usually come when I'm stressed or have been in the sun too.
