Cold sores are most often caused by Herpes simplex virus. Is it possible you've riled up your viruses? I use lysine to keep my herpes viruses under control, but a good antiviral will work.
Yup, I think so. I started taking Lysine yesterday. The one on the right side broke
open today. So if its just a cold sore, and heals like normal, tomorrow itll be scabbed over and gone within 2 days. If it doesnt, well I got a problem then. But I do think its viral. Lets hope.
