Welcome to HCM
You have problem of brown spots appearing in response to stress
. But there no medical explanation of such spots in response to stress. Still the spots may be due to some allergy
reaction. In response to allergy these spots may be appearing and when you pick them they disappear. Or other reason may be some form of Anxiety
in which individual develop feeling like nail biting, hair plucking or like in your case spot picking. There may be possibility that the spots are present before anxiety also but in stages of anxiety you notice them more ofter. For spots I would like to advise you to take dermatological opinion. If dermatologic opinion comes normal then visit a Psychiatrist
for expert opinion.
