Thanks for the query. This presentation can be seen with many skin diseases. The best option is to consult a Dermatologist in person to understand the problem and get it diagnosed. A proper treatment can then be started. Discuss the situation and hope it will be cleared in few days. Don't delay the appointment. You can use any OTC anti-allergic medications. This could be a sign of a disease Called Hidradenitis suppurativa which needs specific treatment by a skin specialist. Hope it helps you Dr MK Agarwala
