Trich, OCD, Stress or all of the above

I guess I need to start by saying that I am not a hair puller, but have fidgeted with my hair my whole life particularly under stress.

I asked my doc a few months about some scalp issues I was having and he said it was trhotillomania, which was just an addition to my depression and PTSD.

The scalp problem has continued and so has my inability to keep from scratching and picking at it. When I saw the doc earlier this week he took another look and said I could have either seborrhoeic dermatitis or psoraisis. He is treating me for the first now and if it doesn't respond, he will treat for the other.

In the meantime, I cannot quit scratching and picking. My scalp is irritated and sore. I am tempted to get my head shaved just to stop the temptation, but I am no Sinead O'Connor.

Any suggestions or similar experiences.

Thanks,

N.
