Causes & associated conditions

A Korean cohort found tinnitus diagnosed six times as often after reflux, yet reflux drugs did not lower it. What the studies show, and where they fall short.

A rare, usually benign tumor is one of the reasons doctors take new one-sided tinnitus seriously — here's what it is and why early imaging matters.

A sudden, piercing sound through a headset can trigger a documented cluster of symptoms — tinnitus among them — distinct from noise damage.

Presbycusis is the third leading cause of chronic disability in older adults, and it travels with tinnitus. The cognitive association is real, widely overstated, and worth reading precisely.

A study of 138,361 tinnitus patients found allergic rhinitis associated with an odds ratio of 1.81 — larger than sleep apnoea or diabetes. What that does and does not mean for a blocked nose and a ringing ear.

A rare but urgent cause of tinnitus and hearing loss — AIED progresses over weeks, and early treatment is what determines whether hearing can be saved.

Bell's palsy can cause tinnitus and sound sensitivity through a well-understood mechanism — and, unlike Ramsay Hunt syndrome, usually resolves fully on its own.

High blood pressure is often mentioned as a tinnitus trigger. The real relationship is more specific — and more relevant to one type of tinnitus than others.

A skin growth in the middle ear that erodes what it touches. The pattern that should raise it, what surgery is aiming at — and why tinnitus is not on the list of things it is aiming at.

Several studies link higher cholesterol and triglycerides to tinnitus, possibly through blood flow to the inner ear. Whether lowering them helps is unproven.

In a 2026 study of 138,361 tinnitus patients, chronic sinusitis was more common beforehand than in controls. What that shows, and how sinuses reach the ear.

Tinnitus is a commonly reported symptom tied to COVID-19 infection — what the research shows about how often it happens, and why.

A large VAERS analysis found no disproportionate tinnitus risk from COVID-19 vaccines — while hundreds reporting new tinnitus described real distress.

Dehydration and electrolyte imbalance are widely claimed as tinnitus triggers online. The real evidence is more limited and specific than most content suggests.

Tinnitus has been linked to dementia, but in the studies that measured hearing the link faded. What the cohorts, the Lancet Commission and ACHIEVE show.

Diabetes is linked to modestly higher odds of tinnitus. What a 2.3-million-person meta-analysis and UK Biobank data show about it, and what they do not.

When earwax causes tinnitus, how drops, irrigation and microsuction compare, and why some people notice ringing after microsuction.

Hydrops is what is happening in the ear. Ménière's is a set of symptoms. For 75 years the first could only be confirmed after death — MRI changed that, and it complicated the tidy version.

Blocked, popping or ringing ears after a cold, flu or flight often mean the Eustachian tube is not equalising. How long it lasts, and when to get checked.

Some people notice tinnitus during heavy lifting or straining — often tied to the Valsalva maneuver's real, measurable effect on pressure in the body.

Labyrinthitis and vestibular neuritis look nearly identical — vertigo, nausea, imbalance — but only one involves hearing loss and tinnitus.

Lyme disease can affect the cochlea, and tinnitus is a common complaint in tick-borne disease clinics. What the evidence shows, and when testing makes sense.

Most of this site is about a sound you live with. Mastoiditis is the opposite — an infection of the bone behind the ear where the useful timescale is hours, and the ear symptoms are the least important part.

Tinnitus is one symptom of Ménière's disease, not a separate condition — here's how to recognize the difference and why it changes the treatment path.

In developed countries about 1 in 10 bacterial meningitis survivors has permanent hearing loss. Why a hearing test after recovery matters.

Two cross-sectional studies, of 4,633 and 558 women, found tinnitus more common with irregular or heavy periods. What they show, and what they cannot.

Migraine and tinnitus turn up together more often than chance predicts. How strong the link is, what might explain it, and when it is something else.

Two reviews looked at hearing and balance symptoms as first signs of MS. Tinnitus is on the list — and it is not the symptom either review is about.

Hearing songs, choirs or an orchestra with nothing playing is usually a hearing phenomenon, not a psychiatric one — here is what is known about it.

How loud sound damages the ear and triggers ringing, what counts as a risky exposure, and a large study suggesting the link runs through hearing loss.

An inherited bone condition in the middle ear causes both hearing loss and tinnitus in most people who have it — and surgery often improves both.

Syphilis can infect the inner ear and cause hearing loss, tinnitus and vertigo. What otosyphilis looks like, who gets tested and how much hearing comes back.

A tube stuck open, not stuck shut — hearing your own voice and breathing inside your head, and getting better when you lie down. The opposite condition to ordinary ETD, with the opposite treatment.

A ruptured eardrum usually heals in weeks, and tinnitus typically resolves right along with it. Real healing-time data, and when it needs more than time.

A leak between the inner and middle ear. One of the few causes of tinnitus, dizziness and hearing loss that surgery can correct — and one whose very existence was debated for decades.

A shingles-related condition affecting the ear and face, with tinnitus as a recognized symptom — and early treatment is linked to better facial recovery.

Hearing loss from damage to the inner ear or auditory nerve, as opposed to a mechanical problem in the outer or middle ear. The type most often associated with tinnitus.

Tinnitus alone is rarely the first sign of a brain tumour, stroke or MS. What scan and population studies found, and the combinations that need prompt care.

Sleep apnea and tinnitus show up together often enough that an apnea evaluation is worth considering, since treating it may help both.

Some tinnitus isn't purely 'in the ear' — it can be modulated by muscles in the neck, jaw, and shoulders. How that's identified.

A spinal CSF leak lowers pressure around the brain, often bringing tinnitus, muffled hearing and a headache that eases lying flat. How it is found and treated.

Stress is closely linked with tinnitus and can make it louder, but it has not been shown to cause it. What cortisol studies, cohorts and animal research show.

Tinnitus alone is rarely a stroke sign. Sudden hearing loss with vertigo can be one: the AICA stroke pattern, the HINTS plus exam, BE FAST and when to call.

Hearing loss developing over hours or days, often with new tinnitus, needs treatment within days for the best chance of recovery — not a wait-and-see symptom.

A rare gap in the inner ear bone can cause strange symptoms — including hearing your own heartbeat, footsteps, and eye movements.

An outer ear canal infection is common and usually minor, and can produce temporary tinnitus alongside its more familiar symptoms.

Ringing after a concert comes with a temporary hearing loss that NIDCD says disappears 16 to 48 hours later. Repeated episodes carry a real risk of the change becoming permanent.

Both an overactive and underactive thyroid are linked to a higher rate of tinnitus — worth knowing if you have a thyroid condition and new ear ringing.

Concussion, whiplash, and other head or neck trauma are well-documented tinnitus triggers — through more than one possible mechanism.

Sudden hearing loss and tinnitus after dental work under local anaesthetic are uncommon but documented, with specific vascular and noise-related mechanisms.

Hearing-restoring ear surgery often eases tinnitus, but it can flare first: in one cochlear implant study, 46.7% had a temporary worsening right after surgery.

Tinnitus in one ear is rarely dangerous, but guidelines single it out. The common causes, the warning signs, and how often an MRI finds anything.

The jaw joint sits right next to the ear, and the anatomy overlaps — why TMJ problems and tinnitus show up together so often.

Tinnitus in one ear only. Assessed more actively than tinnitus in both ears, because one-sided symptoms are more often structural.

A vascular loop on an MRI report is usually a normal variant, not the cause of tinnitus. When nerve compression does matter, and what treatment evidence exists.

Tinnitus and vertigo share the same inner-ear real estate, and people with tinnitus face a meaningfully higher rate of positional vertigo than those without.

Vestibular migraine produces the same ear triad as Ménière's — tinnitus, fluctuating hearing loss, aural pressure — and the features that separate them are specific and checkable.
