I have something like Eczema or Psoriasis, they can't be bothered to determine what exactly. It started when I went to jail back in 2001. I devolved a couple of small patches on my scalp and my thumb nail fell off because my bitch slammed the door on it, (but I was the one taken away)
Anyway, since then I have had a patch on my left thumb and a general spread throughout my scalp. I understand it is genetic and not transferable, triggered by stress it ebbs and wanes.
I have medication but it requires treating the area for four to six hours daily, basicaly it means treating my entire scalp and wearing a shower cap all night every night then showering in the morning for up to six weeks.
I simply can't sustain the effort . Sometimes I feel like Goldmember.
