I wake up to find strange cylindrical burns on my body. The first one appeared on my wrist. It looked like a cigarette had burned me, but I, nor does anyone in my household smoke. I ignored it, but it increased in size.
The second one was found on my lower thigh. It had reacted the same as the one on my wrist, but it grew slightly larger.
Now I have a small one on my chin.
What are they, and how should I go about it? Remember I wake up to them.
