> Act now: A sudden loss or major change in hearing—especially in one ear—should be treated as a medical emergency. Contact an ear, nose and throat physician or another medical professional immediately. If you cannot obtain prompt care, seek evaluation through urgent care or an emergency department. Call emergency services for facial drooping, weakness, trouble speaking, severe headache, fainting or other possible stroke symptoms.
What counts as sudden hearing loss?
Sudden sensorineural hearing loss, sometimes called sudden deafness or SSNHL, is a rapid loss of hearing caused by a problem involving the inner ear or auditory nerve. It may happen all at once or develop over several hours to a few days.
It most often affects one ear. Some people wake up and realize one ear is not hearing normally. Others notice the change during a telephone call, when covering one ear, or after hearing a sudden “pop.”
A formal diagnosis requires professional testing. You do not need to know whether your symptoms meet a technical definition before seeking care.
Warning signs
Sudden hearing loss may feel like:
- A rapid drop in hearing in one or both ears - Muffled or distorted sound - One ear suddenly feeling blocked, plugged or full - Difficulty understanding speech that began abruptly - A new difference between ears - Sudden tinnitus, such as ringing or buzzing - Dizziness, vertigo or imbalance occurring with hearing change - Hearing loss noticed immediately after waking
The ear may look normal and may not hurt. The absence of pain does not make the problem less urgent.
What to do right now
### 1. Contact medical care immediately
Call an ENT, primary-care clinician or other medical provider and clearly say:
> “I experienced a sudden change in hearing that began [time/date], mainly in my [left/right/both] ear.”
Using the words sudden hearing loss helps the office understand the urgency. Ask for immediate clinical guidance and the earliest appropriate evaluation.
If you cannot reach a qualified provider or obtain prompt assessment, use urgent care or an emergency department. The right setting depends on local access and any accompanying symptoms.
### 2. Call emergency services for neurological symptoms
Call 911 or your local emergency number if sudden hearing change occurs with signs such as:
- Facial drooping - Weakness or numbness - Difficulty speaking or understanding speech - New severe headache - Loss of coordination - Fainting or altered consciousness - Sudden major vision change
These symptoms may indicate a neurological emergency and should not be handled as a routine audiology appointment.
### 3. Record when and how the change began
Write down:
- The date and approximate time of onset - Which ear is affected - Whether the change was immediate or progressed over hours or days - Tinnitus, fullness, dizziness, pain or drainage - Recent illness, injury, flight, diving or intense noise exposure - Current medications and recent medication changes - Any neurological symptoms
This information helps the medical team assess urgency and choose testing.
### 4. Do not try to diagnose or treat it yourself
Do not delay care while trying decongestants, ear drops, ear candles, peroxide, cotton swabs or online hearing tests. Do not insert anything into the ear.
Do not take leftover prescription medication or begin corticosteroids without medical supervision. Steroids have important risks and are not appropriate for every person or every cause of hearing change.
Why time matters
The National Institute on Deafness and Other Communication Disorders describes sudden sensorineural hearing loss as a medical emergency. Corticosteroids are a common treatment when the cause is unknown, and NIDCD notes that treatment should begin as soon as possible for the best effect. Treatment delayed more than two to four weeks is less likely to reverse or reduce permanent hearing loss.
The American Academy of Otolaryngology–Head and Neck Surgery Foundation guideline states that clinicians may offer corticosteroids as initial therapy within two weeks of symptom onset. That treatment window does not mean it is safe to wait two weeks for evaluation. It supports seeking care immediately so a qualified clinician can distinguish the type of hearing loss, consider risks and discuss options.
Could it simply be earwax or congestion?
Possibly—but do not assume that it is.
A conductive hearing problem can occur when sound is blocked in the outer or middle ear by earwax, fluid, infection, eardrum problems or pressure changes. Sudden sensorineural hearing loss involves the inner ear or auditory nerve.
Both can feel like a plugged ear. A clinician may examine the ear and use bedside tests, followed by an audiologic evaluation, to help distinguish them.
Even if you have experienced earwax or congestion before, a new sudden difference between ears deserves prompt assessment.
What will the evaluation involve?
The initial assessment may include:
- A detailed history of onset and associated symptoms - Examination of the ear canal and eardrum - Comparison of hearing between ears - Tuning-fork or other bedside assessment - A comprehensive hearing evaluation - Additional testing based on the findings
The clinical guideline recommends obtaining audiometry as soon as possible and within 14 days of symptom onset to confirm sudden sensorineural hearing loss. Again, this is a maximum guideline interval—not a reason to postpone the first medical contact.
What does the hearing test show?
An audiologist measures the softest sounds you hear across different frequencies and evaluates speech recognition. Bone-conduction testing helps separate inner-ear hearing loss from sound blockage in the outer or middle ear.
The evaluation may also include middle-ear testing. Results are shared with the treating medical professional and can guide diagnosis, treatment decisions and follow-up.
An audiologist documents hearing function but does not replace the urgent medical evaluation needed for suspected sudden sensorineural hearing loss.
What causes sudden sensorineural hearing loss?
In many cases, a specific cause is not identified. Possible associations can include infection, autoimmune disease, circulation problems, inner-ear disorders, trauma, certain medications or other conditions.
The lack of an obvious cause does not mean the symptoms are imaginary or that treatment should wait. The immediate priority is confirming the hearing change, excluding urgent causes and discussing appropriate care.
What treatments may be discussed?
Treatment depends on the type of hearing loss, health history, time since onset and possible cause.
### Corticosteroids
Corticosteroids may be offered for sudden sensorineural hearing loss, particularly when the cause is unknown. They may be given by mouth or injected through the eardrum into the middle ear by an ENT.
The potential benefits, limitations and risks should be discussed with a physician. Conditions such as diabetes, glaucoma, infection risk and other health factors can affect the decision.
### Intratympanic steroid treatment
The clinical guideline recommends that clinicians offer or refer for intratympanic steroid therapy when recovery is incomplete two to six weeks after onset. It may also be considered earlier in selected situations, including when oral steroids are not suitable.
### Hyperbaric oxygen therapy
For selected patients, the guideline allows hyperbaric oxygen therapy combined with steroid therapy as an option within two weeks of onset or as salvage treatment within one month. Availability, suitability, risks and evidence should be reviewed with the treating specialist.
### Treatment for an identified cause
If evaluation identifies another condition, care is directed toward that cause. The guideline advises against routinely prescribing antivirals, thrombolytics, vasodilators or vasoactive substances for sudden sensorineural hearing loss.
This article cannot determine which treatment is appropriate for an individual.
Will hearing return?
Recovery varies. Some people regain part or all of their hearing, while others have lasting loss. Prognosis may depend on the severity and pattern of hearing loss, accompanying symptoms, health factors, timing and underlying cause.
Spontaneous improvement can occur, but it is not a reason to delay care. No responsible clinician can guarantee recovery.
Follow-up hearing tests help document change. The clinical guideline recommends audiometric evaluation at the conclusion of treatment and again within six months.
What if hearing does not fully recover?
Audiologic rehabilitation can help address residual hearing loss or tinnitus. Options may include:
- Hearing aids - Contralateral routing systems for single-sided hearing loss - Assistive listening devices - Communication strategies - Tinnitus management - Cochlear-implant evaluation in selected cases - Counseling and support
The recommendation should be individualized after medical and audiologic evaluation.
What not to do
If hearing changes suddenly:
- Do not “wait a few days” to see whether it clears - Do not assume a full or blocked sensation is harmless - Do not rely on an online hearing screening - Do not put objects, candles or unapproved substances in the ear - Do not take someone else’s or leftover medication - Do not let insurance questions delay emergency evaluation - Do not drive yourself if severe dizziness or neurological symptoms make driving unsafe
A simple action checklist
1. Note the time and ear affected. 2. Contact an ENT or medical provider immediately. 3. Use the phrase “sudden hearing loss.” 4. Seek urgent or emergency care if prompt evaluation is unavailable. 5. Call emergency services for possible stroke symptoms. 6. Obtain professional hearing testing as directed. 7. Discuss treatment benefits and risks with the clinician. 8. Complete follow-up hearing tests and rehabilitation if needed.
The bottom line
Sudden hearing loss—particularly a rapid change in one ear—is a medical emergency. It can resemble earwax, congestion or pressure, but the cause cannot be determined reliably at home.
Contact an ENT or another medical professional immediately. Do not wait for an online test or a routine appointment. Prompt evaluation protects the opportunity for time-sensitive treatment and helps rule out other urgent conditions.
After medical evaluation, the Audiology.md provider directory can help you locate an audiologist for diagnostic testing, follow-up and rehabilitation.

Frequently asked questions
Is sudden hearing loss an emergency?
Yes. NIH/NIDCD describes sudden sensorineural hearing loss as a medical emergency. Contact a medical professional immediately, and seek emergency care for neurological warning signs.
Can sudden hearing loss feel like a blocked ear?
Yes. It may cause fullness or a plugged sensation and can be mistaken for wax or congestion. Professional examination and hearing testing are needed to distinguish possible causes.
Should I wait overnight to see whether it improves?
No. Seek medical guidance immediately. Treatment can be time-sensitive, and spontaneous improvement cannot be predicted safely.
Can an online hearing test diagnose sudden hearing loss?
No. An online test cannot examine the ear, distinguish conductive from sensorineural loss or provide medical treatment. It should not delay urgent evaluation.
Are steroids always used?
No. Corticosteroids may be offered, but the decision depends on the clinical findings, timing, health history, potential benefits and risks. Only a qualified clinician should prescribe them.
