I can recall a couple times in my teens where I would pick a particular part of my scalp when I was stressed. I have very thick hair so the ability to hide the damage kept away any intervention into my compulsive behavior. I am now almost 40 and for the last year I have developed a huge compulsion for picking my scalp, mostly at the base of my skull but honestly anywhere I can find a "spot". My boyfriend noticed and insisted he take a look. He was horrified at the damage and took a picture for me. I was shocked.
So I have tried antibiotic ointments, peroxide, shampoos, etc. in the hopes that healing the sores will stop my compulsion. So far, no success. I haven't had a haircut in over eight months because I am terrified of being humiliated. I work a highly stressful corporate job and suspect that the stress is a factor. Anyway, I am in pain a lot....showering is a nightmare.
I just wanted to introduce the worst of me and say how greatful I am to find others (although I am sorry for what you are going through, wouldn't wish it on anybody). Hopefully with enough support we can regain control of our compulsions and get back to positive things in our lives.
