Hi. As per your case history you are having a sebaceous cyst. My treatment advice is - 1. Don t squeeze the lesion as it may worsen the condition. 2. Apply a mild antibiotic cream like fusiderm cream twice daily on it. 3. Only curative treatment is excision under local anesthesia done by a dermato-surgeon. Thanks. Dr. Harshit bhachech. MBBS, DDVL.
