I pick at my arms, chest and by proxy my DH's back. Although it's less picking more 'squeezing' little spots or pores until something comes out.I use a small pair of scissors and a finger nail. I told my PDoc that even just talking about it was making me feel exhilerated (sp?).
I just get this little high whenever I see anything squish out of the spots.
My arms are covered in scars

... luckily I have freckles which hides them very well.
I read that CSP seems to worsen in the evenings, and this is certainly true of me. I also def now see a connection between my stress levels and my CSP. The other day a friend of mine was being a bit of an pain in the butt and I found myself sat there with my scissors, so I called another friend and said . quick I need a chat and cup of tea before I ruin my arms again.
If I can become preoccupied I can stop, but I am easily bored
I haven't had any treatment for it yet thou as I have only recently been diagnosed with Pure O Ocd and BiPOlar II and I realise that my CSP is part of one of these probably the OCD.
Are you in any kind of treatment ATM ? and have you mentioned it to anyone ? what ( if any ) DX do you have ?
