I’m trying to get over mulluscum, tested for STDs all clear?

I’m trying to get over mulluscum and I had a bump on my scrotum. My doc prescribed aldara and after two days my skin there turned red but the bump subsided.Is this how mulluscum looks when it’s fading? I tested for STDs two weeks ago and it was all clear.
