Picking at the skin is quite common. Not all skin picking is disordered skin picking. You should see a doctor about your picking if it starts to cause problems in your day-to-day functions. Such problems might be: not wanting to go outside or meet people because of sores or lesions that are visible, spending hours or days picking at your skin or scanning your skin for imperfections at the cost of doing other things, depression, anxiety, feelings of worthlessness, suicidal thoughts or ideologies, pain, bleeding, and infection. There is more to this list, and it's generally always a good idea to see a doctor about a condition you think you may have, even if you don't fit any or all the symptoms in this list.
