What causes swimmer's ear and what are the symptoms?

ANSWER

Usually, swimmer's ear is caused by bacteria, but it can sometimes be brought on by a virus or fungus. Symptoms you may get include:

  • Itchiness in the ear
  • Pain, which can become severe
  • Trouble hearing (sound may seem muffled as your ear canal swells)
  • Fluid or pus draining out of the ear
