<bot>: Welcome to Chat Doctor .1. Generally these kinds of symptoms are seen in the colonial sinus (infected hair) which can be treated easily in early stages with a course of antibiotics.2. If it gets complicated, it may cause sinus formation and fistulous opening and so all.3. You need a surgeon appointment.4.Don't ignore and leave for complications. Hope it helps you.
