What causes sore lump below the belly button?
Patient: A few days ago I found a small lump about 3 or 4 inches below my belly button. The first day it was painful but now it is not it is also a bit smaller. It does not move and is about the size of a bb. There is also some discoloration like bruising. What could this be. Should I see a doctor right away? Doctor: Hi.This may be due to cellulitis of the abdominal wall. Get checked by the Surgeon to confirm the diagnosis, get a proper course of antibiotic treatment and incision and drainage operation if need be,. You can get this confirmed by high resolution ultrasonography too.
