Hi I just posted about finger chewing in detail as well. I think I stopped finger chewing as I developed this new habit which I have had for about 3 years. I like talking abut the details just because it is interesting and re assuring to find people who suffer from the same thing and I wanted to compare just how similar our habit is in detail.
It started one day at work when I ran my fingers through my hair and noticed an imperfection. (I VERY rarely get spots) so it was novel that one was on my SCALP! I picked it and just thought nothing of it then when my shift had finished I was running my hand through my hair again and noticed that the stuff that came out had dried into a like a scab. I got so much comfort from picking this scab off and sliding it off down my hair, that from then on, I was constantly searching my scalp.
I then started chewing the scabs when I picked them off between my front teeth. Basically it got worse and worse until I was purposely clawing at my scalp in order to make scabs. Each time I picked a scab off, I would wait with anticipation for the few hours to pass until a bigger scab had formed there for me to pick again. Even if it is just dried blood or fluid. Anything with the same sort of crunchy texture.
I feel so PATHETIC when the first thing I do when I wake up is check for scabs, and get annoyed when waiting for my hair to dry when I get out of the shower. I sometimes like to rub the scabs between my finger or examine them closely too. Sometimes if I feel especially stressed I will save scabs on my head and pick them later as a sort of reward, and just keep feeling them on my head.
Before that one day at work, I had never had problems with my scalp, no dandruff either. I don't let people see me eat the scabs. But my friends see me pick my head all the time. If they tell me its disgusting I just tell them to piss off. I've heard of much more disgusting habits than this. Up until now I am surprised I haven't had loss of hair or scarring on my scalp from this. I have a long history of depression, anxiety and OCD which I am on medication for, I suffered trauma as a child, but I really never thought that scalp picking had anything to do with it until I read this website. I thought everyone had habits and mine was just more intense. I have other, much more noticeable disorders that are clearly linked to my OCD, so scalp picking seemed to be one of the more NORMAL activities that I do, lol :(. Please let me know your thoughts.
