I've been scratching at this scab on and off for about a year now because it felt REALLY good. Haven't scratched at it for couple weeks. I've accepted that there will be a permanent scar but I just want to make sure that that's all it is.

When I mean it felt REALLY good I meant intoxicatingly good. Probably the best feeling other than maybe weed (I don't smoke anymore) or sex (haven't done that in a while either). I'm an asian male, 18 years old, 5'11, 170lbs (mostly fat). Here's a picture of the "scar". http://i.imgur.com/SoYb33y.jpg It's on my leg by the way. Also it's smooth but firm and still itches.
