Act before you know the cause
The NIDCD sudden-deafness guidance says sudden sensorineural hearing loss should be considered a medical emergency. It may happen at once or over a few days and often affects one ear. People sometimes delay because the ear feels full and they assume allergy, congestion or wax.
Do not wait for a routine device appointment or spend time testing consumer products. Contact the urgent-care route in your country now. Call emergency services for facial weakness, speech difficulty, severe new neurological symptoms, collapse or serious head injury.
What should you tell the service?
Give the time and date the change began and whether it affects one or both ears. Mention:
- tinnitus or a pop;
- fullness or pressure;
- dizziness or balance change;
- pain, discharge or recent infection;
- recent loud noise, injury or pressure change;
- new medication; and
- facial weakness or altered sensation.
Do not put tools or drops into the ear unless a clinician says they are appropriate for your history.
What may the assessment involve?
A clinician first considers outer- or middle-ear explanations such as wax or fluid. If there is no obvious conductive cause, the NIDCD says pure-tone audiometry should be performed within a few days to identify possible sensorineural loss. Additional tests depend on the findings.
Seek urgent medical assessment now. Do not wait for a routine hearing-aid appointment or assume wax is responsible. The NIDCD hearing-aid overview explains the different roles of an ENT and an audiologist.
Why not quote a treatment plan here?
Treatment depends on diagnosis, timing, contraindications and local clinical guidance. A general article cannot safely choose medication or a route of administration. The useful action is prompt assessment, not self-treatment.
