What causes ear pain at midnight?

Ear pain at night may be caused by improper sleeping posture, ear exposure to cold, external otitis, otitis media, or furuncle of the external auditory canal. Symptoms can be improved by adjusting posture, keeping the ears warm, and medication. If the pain is severe or accompanied by fever or hearing loss, prompt medical attention is necessary.

1. Improper sleeping posture: Prolonged lateral sleeping can compress the ear, impair local blood circulation, and cause aching or fullness in the ear. Adjusting the sleeping position may temporarily relieve symptoms. It is recommended to alternate sleeping positions during the night to avoid prolonged pressure on one ear and reduce strain on ear circulation.

2. Ear exposure to cold: Low nighttime temperatures and insufficient ear warmth can lead to cold stimulation, causing blood vessel constriction and ear pain, possibly accompanied by numbness. It is advisable to wear soft ear warmers before sleep, avoid opening windows that allow cold air to blow directly on the ears, and minimize cold exposure.

3. External otitis: Injury to the ear canal mucosa from ear picking or bacterial infection after water enters the ear can cause inflammation. Swelling and congestion of the mucosa lead to ear pain, which may feel more pronounced at night when surroundings are quiet. Under medical guidance, patients may use medications such as ofloxacin ear drops, cefaclor capsules, or ibuprofen sustained-release capsules to alleviate symptoms.

4. Otitis media: Bacterial invasion into the middle ear due to colds or eustachian tube dysfunction can cause inflammation. Fluid buildup in the middle ear presses on the eardrum, resulting in ear pain, possibly accompanied by tinnitus or ear fullness. It is recommended to use medications such as amoxicillin-clavulanate potassium tablets, phenol glycerin ear drops, or acetaminophen suspension under medical supervision to relieve discomfort.

5. Furuncle of the external auditory canal: Bacterial infection of hair follicles in the ear canal leads to abscess formation. The swelling compresses surrounding tissues, causing severe pain, which may worsen when lying down at night. Patients may follow medical advice to use cefixime dispersible tablets, ichthammol ointment, or loxoprofen sodium tablets to improve symptoms.

Maintain clean and dry ears, avoid water entry, refrain from random ear picking to reduce mucosal injury, eat a light diet avoiding spicy and irritating foods, maintain regular作息 (sleep-wake) routines to enhance immunity, and reduce the risk of ear discomfort.
