Inflammation is divided into acute lymphadenitis and chronic lymphadenitis. Acute lymphadenitis is often accompanied by oral infection and upper respiratory tract infection. Generally, anti infection treatment is taken. If there is local suppuration, it should be cut and drained with drug treatment; However, chronic lymphadenitis is a chronic infection of head, neck, mouth, etc., which leads to long-term lymph node enlargement, local mild pressure and slight pain.
