cold sores
"Woke up at 10pm and had a slight pain in my lower lip to the point that I didn't think I was getting a herpes lip.  By 1pm I could feel the tiniest bump ever but still didn't think I was getting a herp lip. By 2:30pm I ran home and took 1000mg Valacyclovir (which was only half the dose but I did this by mistake).  By 7:30 I got home and definitely had a red and swollen lip and another outbreak right next to it both had little white pimples.  Took the regular dose of 2000mg at 7:30.  Didn't wait 12 hours and took another 2000mg at 4am.  Woke up at 11:30 the 2nd day and there was no pain or swelling but little white dots were still there.  Took another 2000mg at 2pm and the lip is 100% fine, no white dots, lip is 100% fine."
