I have this terrible habit of picking at the skin on my fingers. I used to bite my fingernails and pick at them until they bled, but I quit that. My fingernails look nice . . . . unless you look closely. The skin around the cuticles is a little ragged in places. The bad spots are between my fingers and on the sides. I will pick at them until I rub blisters which become sores. I have callouses on them. I'm not sure what causes me to do this or how to stop. Does anyone else have this problem? Does anyone have any suggestions?
