6 weeks ago, over the course of two nights, I found a black large spot on my thigh. I dug at it until I got all of this thing out. It was deep, and fairly large. Not a pimple, not a cyst. It bled and bled. I later found hundreds of these things all over my body. If I dig the stuff out, it leaves a hole, hurts, and bleeds. They are everywhere. What are they? I'm 56, I've never had blackheads like this. Dr. Says it's not toxic and is not an insect. My next step is to see a dermatologist. Anybody had anything like this? I'm wondering if the house I was living in had mold spores in the air that caused these???????
