About 7 years ago, I got a scab on my calf. I don't remember how it got there. It went away after about 5 months, but left a scar... Since then the "scar" falls off about every couple years and takes a long time to heal. I don't have insurance, and I was just wondering if this has happened to anyone else, and if you know what it is? I have never heard of a scar falling off and scabbing over repeatedly like this.
