When I was 16, I got stabbed in the leg. I got 10 stitches, all the shots, and the stitches were removed and I healed just fine, with slight scarring on the leg (right below the knee). A few weeks ago, my leg itched really bad one night. I must have scratched it a lot because when I woke up, there was blood on my sheets. I looked down at my leg and I had scabs from where I had bleed ... but it was on my scar. Again tonight, leg itches. Must have scratched too hard, and right where the scar is, bleeding again. This was ELEVEN YEARS AGO that I got stabbed. Why is my scar apparently itching now?
