cold sores
"This medication works really well. I woke up this past Saturday with a blister starting to form right under my lip near the corner of my mouth. I of course panicked because getting cold sores really makes me depressed.  They are usually pretty bad and take at least 10 days to heal once I get one.  So for the first time ever, I rushed to the walk-in clinic to try and get a prescription as soon as possible, since I've always been told it will work better if taken immediately. I hate to count my chickens.... but this medication really has seemed to help tremendously.  The blister that formed never really got too bad and is already starting to heal.  I expect it will be gone in another day.  It's not even that noticeable unless you REALLY look.  Amazing."
