With me, such bumps often come with having had a poor diet for a while, stress and an onset of flue. Make sure to take care of yourself and most importantly your sleep and diet. I often find that during a vacation in the alps, I have no symptoms what soever, but after a week of work in Beijing, I would look like a strawberry on a poor day. This all helps you in no way, right now. For me, when I am in a state like you describe, I try to clean it and then stay away from touching it as much as I can. Fresh air and sunshine works best for me. Whatever you do, don’t hide from the world, just go outside. For me, shaving wt works better, as long as I use sharp razors and specific brands of shaving foam.
