Hi, The commonest causes of such a swelling can be one of the following: - Insect bites gives similar picture - Chondritis with seroma formation - An actual abscess formation - Allergic reaction I would advise you the following in such a situation: - Stop popping it as it may open up more of the space and cause worsening of the swelling. - Simple aspiration will tell us the cause whether seroma, hematoma or an abscess. Further management as per the cause found. In seroma, repeated aspiration and pressure dressing may help. Usually done and may rarely need a small surgery to remove part of cartilage. If an abscess or infective then a course of an antibiotic, anti-inflammatory may be needed. Allergic reaction need oral antihistamine and steroids. Take care. Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. T. Chandrakant, General Surgeon
