Facial gland swelling: what to know

Swelling near the cheek, jaw, or under the tongue may involve a salivary gland or nearby lymph tissue. Pain that increases while eating can fit a blocked salivary duct; fever, warmth, redness, or tenderness can occur with infection. Sudden swelling of the face, lips, or tongue may be angioedema, particularly after a food, medicine, or sting. Facial swelling can also accompany sinus inflammation or fluid retention from kidney disease. The location, speed of onset, pain, mouth dryness, and associated symptoms help a clinician narrow the cause.

Arrange a medical review if the swelling is unexplained, painful, recurrent, or not improving. Note when it began, whether it changes with meals, and any new foods, medicines, dental work, or infections. Drink normally unless a clinician has given you fluid restrictions, and avoid pressing or massaging a very tender area. Do not stop a prescribed medicine without advice. A clinician may inspect your mouth, teeth, throat, skin, and glands before deciding whether tests or treatment are needed.

Call emergency services for facial or tongue swelling with breathing difficulty, wheezing, throat tightness, faintness, or trouble swallowing. Rapidly spreading swelling after a food or medicine may be anaphylaxis. Seek urgent assessment for fever with worsening redness, severe pain, pus, dehydration, or swelling that affects the eye or mouth. Use an emergency treatment plan or adrenaline device if one has been prescribed, then seek emergency help.

Ask whether the swelling is in a gland, lymph node, skin, or deeper tissue; whether meals or a recent exposure provide a clue; and whether you need dental, allergy, sinus, or kidney evaluation. Confirm which changes mean you should return urgently.
