Facial swelling or lump

A lump or swelling on the face that wasn't caused by an injury is most likely to be one of the following:

  • Mumps a viral infection that usually affects children and causes swelling of the glands on the side of the face
  • an allergic reaction for example to peanuts, which causes swelling in the deeper layers of the skin ( angioedema )
  • a dental abscess that causes the side of the mouth to swell
  • a salivary gland stone this forms when the chemicals in saliva crystallise and block the flow of saliva from a salivary gland near the jaw, causing pain and swelling around the jaw
