I can't help with your questions but just wanted to say that I remember when you did this, and I can't believe it's 2 1/2 years ago already!

Yeah, me either! I looked back in my post history to find it, and it was July of 2005. Crazy.

I get that on some of my car-accident scars. It's been 10 years, I'll let you know when the itchy red dot thing stops. ;)

(I find it acts up worse when my skin is dry, and often just basic lotion makes it stop).

I have/had a big old keloid on my shoulder from a nasty bike crash back in 1993 where I turned myself into hamburger on some wicked chipseal. I think it finally gradually quit spitting out sand bits and getting the itchy red bump stuff around '01 or '02 - this slowly faded away; for the first 3 or 4 years it would get really irritated at times and would tend to form zits and stuff (ew!!). Within the last 3-5 years it has finally faded to the point where you can barely see it, but for the first couple years I swear to god it looked like an Alien was about to emerge from my right shoulder joint.

Things that exacerbated the bumpy redness: Sweat, heat rash, winter dryness, picking at it and stress. Also, I was young and dumb when I got the initial injury, did a shitty job taking care of it, let it get super infected and put peroxide on it a bunch during the initial healing process (H2O2 is a severe irritant/strong oxidising agent that in repeated use tends to form these granulation tissue/keloid scars), plus I do tend to scar pretty easily

Things that made it better: Vitamin E oil/ointment, moisturising, not picking / itching it and time.

I got second-degree burns to my left hand many years ago and it took about 5 years for the scarred area to stop hurting when it was cold. For some reason, burns seem to take an extra long time to fully heal, so I guess just be patient and look after yourself.

Seconding the vitamin E - but use the capsules you'd take as a supplement because they contain a much higher concentration of vitamin E than body oil. Pop the capsule with a pin and rub the oil in.
