Hi. Thanks for your query. Noted your history of small painless lump under the skin besides right nostril for the last few weeks. Since the swelling is painless, the most probable reasons for such a swelling is usually a cyst called a sebaceous cyst or a nasolabial cyst. The sebaceous cyst is mobile and can be easily removed. The one called as nasolabial cyst needs planning, CT scan of hte underlying bones and thorough removal with drilling of hte underlying bone to avoid the recurrence. I would advise you to consult an ENT Surgeon to get a confirmed diagnosis and plan for the surgery accordingly. Do not fondle the area.
