Ringing in the ears during an illness usually traces back to pressure changes in the middle ear, inflammation triggered by your immune system, or, less commonly, a virus reaching the delicate structures of the inner ear itself. The medical term for that ringing, buzzing, or whooshing sound is tinnitus, and it shows up alongside colds, sinus infections, the flu, and even COVID-19 more often than most people realize. In the majority of cases the ringing fades as you recover, but understanding the different mechanisms behind it helps you know when to wait it out and when to get it checked.
Eustachian Tubes and the Pressure Problem
The most common reason your ears ring when you’re sick has nothing to do with the inner ear at all. A narrow passage called the Eustachian tube connects the back of your throat to the air-filled space behind your eardrum. Its job is to equalize pressure on both sides of the eardrum and drain any fluid that collects in the middle ear. When you have a cold or sinus infection, the tissue lining this tube swells, and mucus thickens. The tube partially or fully blocks, trapping fluid and creating a pressure difference that pulls on the eardrum. That tension distorts the way sound vibrations travel and can produce a persistent ringing, clicking, or muffled sensation.
You’ve felt a mild version of this on an airplane or driving through mountains. The difference during illness is that the swelling can last days or weeks, and the trapped fluid may not drain until the infection resolves. Swallowing, yawning, and the Valsalva maneuver (gently blowing with your nose pinched shut) all work by briefly opening the Eustachian tube, and doctors sometimes recommend these as a first-line approach for tube dysfunction before considering anything more invasive.1Clinical and Experimental Otorhinolaryngology. Navigation-Assisted Balloon Eustachian Tuboplasty for Eustachian Tube Dilatory Dysfunction If the tube stays blocked long enough, the fluid behind the eardrum can become a middle ear effusion, sometimes called “glue ear” in children, which dampens hearing and intensifies the perception of internal sounds like blood flow and muscle contractions.
How Your Immune Response Creates the Ringing
Even without a blocked Eustachian tube, your body’s fight against an infection can set off tinnitus through a different route: inflammation. When your immune system detects a pathogen, it floods tissues with signaling molecules called cytokines. Some of these, particularly TNF-alpha and IL-1-beta, have been found at elevated levels in the cochlea and along the central auditory pathway in animal models of tinnitus.2PubMed Central. The Role of Inflammation in Tinnitus: A Systematic Review and Meta-Analysis These inflammatory molecules don’t just sit there. They appear to make auditory nerve cells overly excitable, essentially turning up the gain on the hearing system so it starts generating phantom signals that your brain interprets as sound.3Current Otorhinolaryngology Reports. Neuroinflammation in Tinnitus
This helps explain why ear ringing sometimes accompanies illnesses that don’t obviously involve the ear at all, like the flu or a stomach bug with a high fever. Your immune system is revving system-wide, and the auditory pathway can get caught in the crossfire. In rodent studies, when researchers blocked those pro-inflammatory cytokines with drugs or genetic modifications, the physiological and behavioral signs of tinnitus were reduced.3Current Otorhinolaryngology Reports. Neuroinflammation in Tinnitus That finding is still in the animal-research stage, but it underscores that the ringing is not “just in your head” in any dismissive sense. There’s a real biological process driving it.
When a Virus Attacks the Inner Ear Directly
Beyond pressure and inflammation, some viruses can physically invade the structures responsible for hearing. A review of viral causes of hearing loss found that certain infections directly damage inner ear structures, while others trigger inflammatory cascades that cause the damage secondarily, and still others increase susceptibility to bacterial or fungal co-infections that then harm the ear.4PubMed Central. Viral causes of hearing loss: a review for hearing health professionals Measles, mumps, rubella, and cytomegalovirus are classic culprits, though widespread vaccination has made most of these less common. Herpes viruses, including the one that causes chickenpox and shingles, are another well-documented group that can affect hearing.
The damage from a direct viral attack tends to be more serious than the pressure-related ringing from a head cold. It can cause sudden sensorineural hearing loss, where one ear rapidly loses the ability to detect sound. Tinnitus often accompanies this kind of hearing loss because the brain, deprived of normal input from damaged hair cells or nerve fibers, begins generating its own signals to fill the gap. If you notice a sudden, significant drop in hearing in one ear during or after an illness, that warrants urgent medical attention rather than a wait-and-see approach.
COVID-19 and the Ears
COVID-19 added a fresh chapter to the connection between viral illness and ear symptoms. Research using human inner ear tissue demonstrated that hair cells and Schwann cells in the vestibular system express the receptors SARS-CoV-2 uses to enter cells, and that these cells can be infected by the virus in laboratory conditions.5Communications Medicine. Direct SARS-CoV-2 infection of the human inner ear may underlie COVID-19-associated audiovestibular dysfunction Separate animal studies showed that when SARS-CoV-2 was introduced through the nose, it reached the inner ear and specifically targeted spiral ganglion neurons, the nerve cells that relay sound information from the cochlea to the brain.6PubMed. SARS-CoV-2 directly infects the inner ear and causes hearing dysfunction
What this means practically is that tinnitus, muffled hearing, and dizziness reported by some COVID patients aren’t just a side effect of congestion or being bedridden. The virus appears capable of reaching auditory and balance organs directly. Reports of these symptoms span the original strain through Omicron-era variants. Most people recover their hearing, but a subset experience lingering tinnitus as part of long COVID. If ear ringing starts during or shortly after a COVID infection and doesn’t improve within a few weeks of recovery, it’s worth flagging for a doctor.
Sinus Infections and the Overlap With Migraine
Sinus infections deserve their own mention because they’re one of the most common illnesses that bring ear symptoms along for the ride. The sinuses, Eustachian tubes, and middle ear are all connected through the same drainage system in the back of the nose and throat. When the sinuses are inflamed and packed with mucus, the resulting pressure and swelling easily spread to the Eustachian tube opening, producing the pressure-related ringing described earlier.
There’s an interesting wrinkle here. Many people who believe they have recurrent sinus infections actually have migraine. A registry-based study found that patients reporting facial pressure and sinus-type pain had significantly higher rates of vestibular and ear symptoms, along with more severe headaches and higher scores on migraine screening tools, compared to those without facial pressure complaints.7Frontiers. Facial/sinus pain or pressure and migraine: exploratory findings from the HEADS registry Migraine can cause ear fullness, tinnitus, and even temporary hearing changes on its own. So if you notice that your “sinus infections” come with ear ringing, light sensitivity, and nausea but no fever or discolored mucus, it may be worth discussing migraine with your doctor rather than reaching for another round of antibiotics.
Medications You Take While Sick Can Contribute
Here’s a layer many people miss: the drugs you take to feel better during an illness can themselves trigger or worsen ear ringing. Over-the-counter pain relievers are the biggest everyday example. A large longitudinal study of women found that frequent use of non-aspirin NSAIDs (like ibuprofen) was associated with a modestly higher risk of developing persistent tinnitus, with the risk rising in a dose-dependent pattern. Frequent acetaminophen use showed a similar association.8PubMed Central. Longitudinal Study of Analgesic Use and Risk of Incident Persistent Tinnitus The increase in risk was not dramatic for occasional use, but someone popping ibuprofen or acetaminophen multiple times a day for a week-long illness is hitting the frequency range where the association becomes measurable.
Aspirin at high doses has long been recognized as a tinnitus trigger, though the effect is usually reversible once the dose drops. The bigger concern in clinical settings involves prescription medications with stronger ototoxic potential. Aminoglycoside antibiotics, sometimes used for serious bacterial infections, and platinum-based chemotherapy drugs like cisplatin are known to damage outer hair cells in the cochlea, starting in the region responsible for high-frequency hearing.9PubMed Central. Cisplatin and aminoglycoside antibiotics: hearing loss and its prevention Most people won’t encounter these drugs during a routine illness, but if you’re hospitalized for a serious infection and notice new tinnitus while on IV antibiotics, mention it. Doctors can sometimes switch to a less ototoxic alternative.
The practical takeaway: if your ears start ringing while you’re sick, consider whether the symptom lines up with the illness itself or with the timing of a medication. If it started after you began taking something new, that’s useful information for your doctor.
What Actually Helps
Most illness-related tinnitus resolves on its own once the underlying infection clears. That’s reassuring but not especially helpful when you’re lying in bed with a ringing that won’t quit. A few approaches can ease things in the meantime.
For pressure-related ringing from congestion, the goal is to get the Eustachian tubes open and draining. Nasal saline rinses (using a squeeze bottle or neti pot) thin mucus without medication. Steam from a hot shower or a bowl of hot water can temporarily reduce swelling in the nasal passages. Staying well-hydrated keeps mucus thinner and easier to move. These aren’t dramatic interventions, but they address the mechanical cause.
You might assume that nasal decongestant sprays would be the obvious fix, and they can provide temporary relief of nasal congestion. However, for fluid that’s already trapped behind the eardrum, topical decongestants have shown limited benefit. A controlled trial in children with persistent middle ear effusion found that rates of improvement were similar in the decongestant and placebo groups.10PubMed. Topical phenylephrine for the treatment of middle ear effusion That doesn’t mean decongestant sprays are useless for nasal stuffiness, but they’re not a reliable fix for the ear ringing specifically. And using them for more than a few days can cause rebound congestion, making the whole situation worse.
For nighttime relief, background sound can make the ringing less intrusive. A fan, white noise machine, or quiet music gives the brain something external to latch onto instead of amplifying the phantom signal. A randomized trial of acoustic therapy for acute tinnitus tied to sudden hearing loss found limited short-term benefits across the full study group, though patients with more severe hearing loss who continued acoustic therapy at home did show higher tinnitus resolution rates in the longer term.11BMC Medicine. Efficacy of standard care versus acoustic therapy on acute tinnitus in idiopathic sudden sensorineural hearing loss: a randomized controlled trial Sound masking won’t cure the ringing, but it can take the edge off while your body heals.
When to See a Doctor
Most illness-related ear ringing doesn’t need medical intervention beyond treating the illness itself. But certain patterns signal something more serious:
- Sudden hearing loss: If one ear goes noticeably quiet or deaf over hours to days, especially during or after an infection, this could be sudden sensorineural hearing loss. Treatment with corticosteroids is most effective when started early, ideally within the first two weeks.
- Ringing lasting well beyond recovery: If the illness has cleared but the tinnitus persists for more than a few weeks, it may have shifted from an acute symptom to something requiring its own evaluation.
- Pulsatile tinnitus: A rhythmic whooshing or thumping in time with your heartbeat is a different animal from the steady ringing caused by congestion or inflammation. It can have vascular causes that are worth investigating.
- Ringing in only one ear: Bilateral ringing during a cold is common and usually benign. Persistent unilateral ringing, particularly with hearing loss, needs a hearing test and possibly imaging.
- Ear drainage or severe pain: These suggest a middle ear infection that may have ruptured the eardrum, or a more complicated infection requiring treatment.
For sudden sensorineural hearing loss specifically, clinical guidelines recommend against routinely prescribing antivirals, blood thinners, or vasodilators, even when a viral cause is suspected.12PubMed. Clinical Practice Guideline: Sudden Hearing Loss (Update) The evidence for those treatments hasn’t held up. Corticosteroids, either oral or injected through the eardrum, remain the main treatment with supported evidence. If a doctor suggests antivirals for sudden hearing loss, it’s reasonable to ask what evidence supports the choice.
Why Fever Itself May Play a Role
There’s a less-studied but plausible contributor worth knowing about: fever. Elevated body temperature changes the biochemical environment of the cochlea. The inner ear depends on a precise balance of ion concentrations in its fluids to convert sound vibrations into nerve signals. Fever can alter blood flow to the cochlea and shift the metabolic demands on hair cells. Some researchers suspect this is one reason tinnitus can appear during illnesses that don’t directly involve the ear or sinuses at all, like urinary tract infections or gastroenteritis. The evidence here is mostly indirect and extrapolated from what we know about the cochlea’s sensitivity to metabolic disruption, but it fits with the common observation that ear ringing peaks when a fever spikes and fades as temperature normalizes.
Chronic Illness Versus a Single Bout of Sickness
A single cold that causes a week of muffled hearing and tinnitus is annoying but usually harmless. The picture changes for people who are chronically ill or immunocompromised. Repeated ear infections can cause cumulative damage to middle ear structures. Chronic inflammation, as seen in autoimmune conditions, may keep the auditory system in a state of low-grade irritation that makes tinnitus more likely to develop and harder to resolve. People on long-term medications with ototoxic potential, whether for autoimmune disease, chronic pain, or cancer, face compounding risk that a healthy person recovering from a head cold does not.
For children, recurrent middle ear infections are one of the most common reasons for doctor visits, and persistent fluid buildup can affect hearing during critical years of language development. Adults with diabetes, kidney disease, or conditions requiring frequent antibiotic courses should be especially attentive to changes in hearing during illnesses, because the baseline vulnerability of their inner ears may already be elevated.
What Doesn’t Work Despite Being Widely Believed
A few popular remedies for illness-related ear ringing have weak or no evidence behind them. Ear candles, which involve placing a hollow cone in the ear canal and lighting the other end, have been studied and found to produce no suction effect on the ear canal and no removal of earwax. They can, however, deposit candle wax in the ear and cause burns. Hydrogen peroxide drops are sometimes suggested for ear ringing during a cold, but they address earwax, not middle ear fluid or cochlear inflammation, and they can irritate the ear canal lining if used frequently.
Herbal supplements marketed for tinnitus, particularly ginkgo biloba, have been tested in multiple trials. The evidence is mixed at best, and systematic reviews have generally concluded that ginkgo doesn’t reliably outperform placebo for tinnitus relief. Some people swear by it, which is fine, but it’s worth knowing the evidence doesn’t support a strong expectation of benefit.
Perhaps the most important misconception is that antibiotics will help with ear ringing from a viral illness. The common cold and flu are caused by viruses, not bacteria. Antibiotics do nothing for viruses and carry their own risks, including disrupting gut bacteria and contributing to antibiotic resistance. Antibiotics are appropriate for confirmed bacterial ear infections or sinus infections, but many cases of sinusitis are also viral and resolve without them. If your doctor recommends watchful waiting rather than an immediate antibiotic prescription for mild ear symptoms during a respiratory illness, the evidence is on their side.
