I got a bug bit on my hand that refused to heal and I he'd terribly it's been going on for over a month peryoticly I try to dig out what feels to be a hard(like a fingernail) mass out off the wound. Tonight I had my son dig it out what we found was a hair deep(maybe a centimeter) under the skin on the edge of the wound and then fished out a piece of skin that looked like a worm almost. After dining the skin and hair out its stopped itching completely. My doctor says that it's eczema but I'm not so sure about that.
