Is it a fungus, bacteria or a curse?

Mine looks exactly like the photos in the What does it look? section and it is not bacteria - I had a biopsy of my active lesion. I have started using acyclovir tablets(cold sore treatments) 4 months ago. I start taking the tablets as soon as feel I’m going to have a breakout. At the beginning my skin improved very much, but since 3 weeks ago I am getting severe breakouts again.

Have any of you ever tried cold sore/ herpes treatments?
