  • Needle aspiration may show what is causing your abscess. A needle will be used to take the fluid out of the abscess. The fluid is sent to a lab for tests.
  • A CT scan or ultrasound may show the peritonsillar abscess. You may be given contrast liquid to help the abscess show up better in the pictures. Tell the healthcare provider if you have ever had an allergic reaction to contrast liquid.


  • IV fluids may be given if you are unable to eat or drink anything.
  • Incision and drainage may be needed to drain your peritonsillar abscess. Your healthcare provider will make a cut in the abscess to allow the pus to drain. Ask your healthcare provider for more information.
