What causes numbness in both cheeks, and what should I do about it?

Generally, a tingling sensation in the cheeks may be caused by cold weather, excessive tension, food allergies, idiopathic facial nerve palsy, diabetic neuropathy, and other factors. Management can vary depending on the specific cause. It is recommended to seek timely medical evaluation and receive treatment under the guidance of a healthcare professional.

1. Cold weather: In cold conditions, blood vessels constrict, which may slow circulation and temporarily impair normal nerve function, leading to a numb or tingling sensation in the face. This is usually temporary. Keeping warm is recommended to alleviate symptoms.

2. Excessive tension: High levels of stress or anxiety can cause muscle tension and disrupt blood circulation, potentially resulting in facial numbness or discomfort. Practicing deep breathing exercises or taking a walk may help relieve tension.

3. Food allergy: Allergic reactions to certain foods may trigger facial muscle contractions or nerve excitation, causing a tingling sensation in the cheeks. Treatment may include antihistamines such as cetirizine hydrochloride oral solution, loratadine tablets, or promethazine hydrochloride tablets, as advised by a doctor.

4. Idiopathic facial nerve palsy: Idiopathic facial nerve palsy is a sudden-onset condition involving facial weakness or paralysis, possibly due to facial nerve damage or infection. Symptoms include numbness, tingling, or loss of muscle control on one or both sides of the face. Patients may be prescribed medications such as vitamin B12 tablets, mecobalamin tablets, or vitamin B1 tablets under medical supervision.

5. Diabetic neuropathy: Diabetes, often related to genetic and metabolic factors, can lead to nerve damage known as diabetic neuropathy. This condition may cause abnormal nerve sensations, including facial tingling or prickling. Managing blood glucose with medications such as insulin glargine injection, acarbose capsules, or insulin aspart injection—as directed by a physician—can help control symptoms.

In daily life, maintaining a regular sleep schedule and engaging in moderate physical activity may help prevent discomfort. Additionally, gently massaging the face can improve local blood circulation and aid in symptom relief.
