text: why is the scar on my knee spotted? i fell and got a big carpet burn on my knee a few weeks ago. it's a scar now, but it's dotted/speckled. i've never seen anything like it before so i was just wondering what it was.   when it was still a "fresh" burn, that same area would always turn white--milky white, not clear white--after a shower. is it infected or something? it gives me the chills when i look at it. when a cut is fresh it usually does turn white after you take a shower. so its not infected and when you get a carpet burn the scar is sometimes dotted because my carpet burns scar is dotted as well. i was sliding on the carpet floor somewhere. and well yea.so its dotted in a streak manner. but thats my answer.
