A.

Most insect bites produce only minor irritation, with symptoms such as:

  • Swelling at the site of the bite.
  • Itching or burning.
  • Local numbness or tingling.


Bites of poisonous spiders and scorpions may produce these symptoms:

  • Intense pain at the site of the wound.
  • Stiffness or joint pain.
  • Muscle spasms.
  • Abdominal pain, nausea, or vomiting.
  • Fever or chills.
  • Difficulty breathing or swallowing.
  • A spreading, ulcerated wound or tissue death.
  • Dizziness, impaired speech, or convulsions.


An insect or spider bite can rarely cause a potentially fatal allergic reaction known as anaphylactic shock. Its symptoms include:

  • Rapid swelling of the lips, tongue, throat, or around the eyes.
  • Difficulty breathing.
  • Wheezing or hoarseness.
  • Severe itching, cramping, or numbness.
  • Dizziness.
  • A reddish rash or hives.
  • Stomach cramps.
  • Loss of consciousness.

Please call 911 immediately if you are having chest pain, difficulty breathing, severe bleeding, sudden weakness or numbness, or if you think you have a medical emergency.
