I've been put on a 5 day course of Aciclovir 400mg tablets for my herpes outbreak and for the first 2 days it seemed to have cleared but I obviously carried on my course and on the 3rd and 4th days it started to flare up again and now it is the 5th day and it is really itchy and it is starting to hurt again. Anyone know why this could be happening?? And anyone know what I can do??
