black fly

I'm not sure they are actual black flies. They are tiny little triangular monsters that are everywhere around the house. And sometimes inside. I had one really bad sting, so I kept a close eye on the bastards. And then one of them stung in my left arm, and I killed it on sight. Almost in the intstant it landed on my arm. I immediately put After Bite on the area. At first I thought I was okay, it happened the day before yesterday. Yesterday it itched, but not too bad. And today it's driving me crazy! I try not to touch it, try even not to have my arm touch my left boob, but to achieve that, I have to keep my arm up in the air, which I don't manage all of the time. The bite is red and swollen, and what is very weird, all the insect bites I had over the past weeks and had long healed, have started itching again. Ooooh, I want to scratch everywhere...! I've taken a Benadril Night, that should knock me unconscious.
