Umbilical hernias often occur because there is a weak spot near the navel and a defect in the abdominal wall, allowing abdominal contents to protrude through this weak spot and form a lump on the surface. If the hernia is not strangulated, the contents can be reduced when the patient lies flat, causing no obvious symptoms. However, if the protruding contents cannot be reduced, there may be strangulation or the hernial ring may be too small. Pressing on the protruding lump at this time may cause pain. This pain generally becomes more pronounced the longer the protrusion persists. Of course, if the hernia is completely strangulated, causing circulatory problems, the pain may significantly decrease, but this does not indicate an improvement in condition. Therefore, if an umbilical hernia becomes painful upon pressing, surgical treatment should be considered to avoid complications.
