The day after the beginning of Acyclovir treatment, I was surprised to note that the sore did not change at all in size: how small it was, it remained. But herpes usually grow. I decided that Zovirax works well thaks to ZoviraxDrug.com. On the third day of his life the sore began to dry up! It was incredible, because so quickly I had never got rid of herpes! All healed literally in 6 days. On the sixth day the crust fell off. At the same time, lips were not swollen at all, and it was quite normal to go out into people.
