Two years ago, my son fell while playing outside and scraped his cheek pretty good. We cleaned it real well and it healed pretty nicely, we thought. We knew it would leave a small scar that, over time would lessen in appearence. About 6 months ago, it scabbed over. We put neosporin on it and it looked okay after a week. It is now raised, and it looks like it is a dry patch on his cheekbone. He complains that it itches all the time and because he is constantly scratching it, it looks like it is beginning to scab over again. Thoughts?
