All my life. Mostly pick at mosquito bites, as I live in the tropics. Things improved greatly when I moved to Texas, but as soon as I moved back, there I was again. Then again, it probably is also related to wearing more pants/working, etc. in Texas vs. not working/wearing shorts in the tropics.
Also do it with my cuticles and around my nails.
After the skin I started with my scalp
I can't stop. I try and try, but I can't.
I have only had a couple of major scares where I caught MRSA because of it
Sadly, after a while, I went right back to it.
My son who is diagnosed PDD-NOS, HFA or AS, depending on who you ask lol, used to pick at his scabs too. Somehow he stopped. I am now noticing his lips are always dry and I continue to bug him to put something on his lips. Sometimes they look a bit bloody. I worry about it, but I know a psychologist will just give him meds and not sure that will really help. Looking for a way to help him.
PS my mother, whom I suspect is on the spectrum or maybe combo AS/ADHD, has always done the same, but just to her face...ugh
