Why Are My Lymph Nodes Swollen?

The lymph nodes in your neck may swell in response to any problem affecting the mouth, head and neck. These problems include:

  • Common cold
  • Sore throat
  • Infection
  • Injury
  • Tumor

When to See a Doctor About Swollen Glands

Swollen glands are typically a sign that your body is in the process of fighting off an infection or illness. In most cases, they will return to their normal size once your body is cleared of the problem. However, you should see a doctor if your glands:

  • Swelled up suddenly
  • Are much larger than normal
  • Are very hard and immobile
  • Remain swollen for over a few days

In addition, swollen glands accompanied by night sweats, persistent fever, sudden weight loss and arm or groin swelling warrant medical attention.

What to Expect at Your Appointment

Your SFENTA™ ear, nose and throat doctor will begin by identifying the underlying cause of your swollen glands. To that end, he or she may recommend the following tests:

Biopsy

This test involves removing lymph node tissue and examining it under a microscope.

PET Scan

A PET scan can help identify cancers, heart disease and brain disorders that may be contributing to your swollen glands.

CT Scan

A CT scan creates detailed images of your body and can help aid in a diagnosis.
