Suddenly feeling intense itching inside the ear at night while sleeping

Itching in the ear at night may be caused by excessive cerumen in the external auditory canal, or conditions such as external otitis eczema or otitis media, requiring targeted medical treatment.

1. Excessive Cerumen in the External Auditory Canal

If the external auditory canal is not cleaned for a prolonged period, excessive cerumen may accumulate and irritate the skin lining the canal, leading to itching. However, this condition is generally mild and symptoms usually improve after proper cleaning.

2. External Auditory Canal Eczema

Exposure to external allergens may trigger allergic dermatitis, resulting in eczema of the external auditory canal. It is recommended to avoid the allergen promptly and, under medical guidance, treat with medications such as mometasone furoate cream or dexamethasone tablets.

3. Otitis Media

When otitis media is caused by bacterial infection, inflammation may also lead to ear itching. As directed by a physician, treatment may include ear irrigation with ofloxacin or hydrogen peroxide solution.

In addition, patients with diabetes may experience itching due to excessively dry skin. It is recommended to control blood glucose levels under medical supervision using medications such as mitiglinide calcium capsules or repaglinide tablets.
