herpes simplex
"I have suffered from impetigo a yellow brown crusting severe type of cold sore ever since I was a child. I get them when the seasons change or when I'm a little stressed out, or even just because the humidity in my house changes. It really sucks most of the time and I have went to my doctor and have gotten a prescription for antibiotic cream and even pills for impetigo. But they have never worked as effective as abreva has. If you want your cold sore to just go straight to the scabbing stage after it occurs then use abreva. It's only been the second day and it's already pretty much gone."
