[/INST] Respected User, hi I evaluated your query thoroughly.*Clinically it is Infected Sebaceous Cyst.*You can take temporarily analgesics for pain relief, but I strongly suggest   you to consult Consulting Surgeon as early as possible because many  cases are in need of definitely proper treatment & surgery at times.
