Sty

Signs and symptoms of a sty include:

  • A red lump on your eyelid that is similar to a boil or a pimple
  • Eyelid pain
  • Eyelid swelling
  • Tearing

When to see a doctor
Most sties are harmless to your eye and won't affect your ability to see clearly. Try self-care measures first, such as applying a warm washcloth to your closed eyelid. Contact your doctor if:

  • The sty doesn't go away in a week
  • Redness and swelling extend beyond your eyelid and involve your cheek or other parts of your face
