A bee sting usually causes immediate sharp pain , then redness, swelling, and itching around the sting site. In most people it stays local and improves with basic first aid, but a small number of people can have a serious allergic reaction that needs emergency treatment.

What you may feel

  • Pain or burning right away.
  • Mild swelling, redness, and itchiness.
  • A larger local reaction can make swelling spread farther than the sting spot.

When it becomes serious

Seek emergency help right away if there are signs of anaphylaxis , such as:

  • Trouble breathing.
  • Swelling of the tongue or throat.
  • Trouble swallowing.
  • Tightness in the chest.
  • Rash or widespread hives, vomiting, abdominal pain, or collapse.

What to do

  • Remove the stinger quickly if it is still in the skin.
  • Wash the area, apply a cold pack, and avoid scratching.
  • If you know you’re allergic and have an epinephrine auto-injector, use it as directed and call emergency services.

Quick note

For most people, a bee sting is painful but not dangerous. The main thing to watch for is an allergic reaction, especially in the first hour or two after the sting.
