What to know about swollen glands

Lymph nodes filter fluid and help the immune system respond. Nodes in the neck may enlarge during a sore throat, tonsil infection, cold, or another infection affecting the head and neck. They can be tender and move slightly under the skin. A clinician considers whether swelling is on one or both sides, how quickly it appeared, and whether fever, rash, night sweating, weight change, or fatigue is present. Swollen glands do not reveal the cause on their own.

Rest, drink fluids, and treat discomfort with a medicine that is suitable for you. Avoid repeatedly pressing or squeezing the node, which can irritate the area. Arrange a review if the swelling keeps growing, feels hard or fixed, returns repeatedly, or remains after an illness has settled. Depending on symptoms, your clinician may examine your throat and ears or consider tests. Helpful background includes [Common Cold](/conditions/common-cold/) and [Tonsillitis](/conditions/tonsillitis/).

Seek urgent care for difficulty breathing or swallowing, drooling, severe neck swelling, confusion, or rapidly worsening illness. Prompt medical review is also appropriate for swollen glands with a persistent high fever, unexplained bruising, marked weakness, or swelling above the collarbone. A clinician can distinguish common infection-related enlargement from causes needing further investigation.

Ask which infection could be affecting the area, how long the node should be monitored, whether you need a throat or blood test, and which changes should bring you back sooner.
