Growing up, the back of my arms were always a little bumpy, a little red. A little embarassing if anything, but no big deal. I can't even remember when it started, but it was probably my first year of working full time after university that I found it incredibly relaxing to pop the little red bumps on the back of my arms. These little red bumps eventually turned into blemishes/pimples, which I popped like a zit. This is gross, I know, but it is so extremely satisfying to do for me. I'd do it compulsively to the point where the back of my arms looked like a battle field of red marks, showing where I was picking my skin. These marks then turned to finger nail shaped scabs, all over the backs of my arms. It has gotten to the point where others have noticed and I cannot stop! I sometimes choose longer sleeved shirts on hot days, or try to hide my arms when wearing a t-shirt. This last week at work was particularly stressful, and I found that my arm picking increased, meaning that this must be stress related because I feel so relieved when I do it. I cannot stop for the life of me - can anyone help? I've started to talk about it with family and friends, but I can't seem to stop.
