How can a cold cause an earache?

Colds can cause ear and eye pain, which may be caused by acute secretory otitis media, herpetic tympanitis, acute suppurative otitis media and other reasons.

Acute secretory otitis media: After a cold, pathogenic microorganisms enter the middle ear cavity through the Eustachian tube and cause dysfunction of the Eustachian tube, resulting in middle ear infection. It is mainly characterized by hearing loss, middle ear effusion, tinnitus, etc. Some patients may also show symptoms of earache.
2. Herpetic tympanitis: If the cold is caused by viral infection, then the viral infection may also lead to herpetic tympanitis, which is mainly characterized by earache, hearing loss, fever, etc., and the patients usually have more serious earache.
