A little numbness on both sides of the cheeks may be caused by cold stimulation, allergy, diabetic peripheral neuropathy and other reasons. 1. Cold stimulation: When you are in a cold environment or your face is blown by cold wind, you may experience numbness on both sides of your cheeks, which is related to the slowing down of blood circulation in the face due to cold stimulation. 2. Allergy: When the body is allergic to certain foods and drugs, numbness on both sides of the cheeks may also occur. 3. Diabetic peripheral neuropathy: distal symmetrical polyneuropathy is common, which can be manifested as numbness on both sides of the cheeks. If the numbness on both sides of the cheeks is more serious and lasts for a long time, it is recommended that the patient should consult a doctor for a clear diagnosis and treatment.
