The term ototoxicity describes inner ear damage from drugs that can cause tinnitus (ringing in the ears), and affect hearing and sometimes balance. Medications more likely to cause ototoxicity include aspirin; the antibiotics azithromycin and clarithromycin; certain chemotherapy drugs; loop diuretics such as furosemide (Lasix); and some biologics. These drugs can damage hearing by injuring hairlike projections in the inner ear. People taking ototoxic drugs should get their hearing tested before, during, and after using the drug.

Hyperacusis describes sensitivity to some or all sounds, no matter the volume. Depending on the person, sounds might be uncomfortably loud; cause pain in the ear, head, or another part of the body; trigger negative emotional responses; or make someone dizzy. These reactions might be due to irritated or overactive nerve fibers or muscles in the ear. While doctors have few treatments for hyperacusis, certain strategies help, such as avoiding sound triggers, wearing hearing protection, and engaging in sound therapy.

Havard researchers have identified biomarkers that appear to capture tinnitus severity for the first time. Scientists made the connection after analyzing the facial responses and pupil dilation of study participants as they listened to pleasant, neutral, or unpleasant sounds. The findings, when fed to a computer model, accurately predicted the severity of symptoms participants had reported on questionnaires. Scientists hope the biomarkers will lead to tools that gauge tinnitus severity and treatment effectiveness.

Earwax should be removed only if it causes problems with hearing, ringing in the ears, or an earache. To unblock the wax, people can use an over-the-counter ear-cleaning treatment to flush it out. If this is not successful, see your doctor.

Nosebleeds are common, and dry air is the most prevalent cause. Other triggers include allergies, blood-thinning medications, or a deviated septum. People with frequent, heavy nosebleeds may need evaluation for a more serious underlying condition.

People may choke on their own saliva when talking quickly, laughing, or turning their head. Other causes include postnasal drip or dry mouth, which medications may trigger. Certain health conditions can also affect swallowing.

A small randomized trial in 2024 found that both self-adjustment and in-situ audiometry were effective strategies to match self-fitting hearing aids to personal hearing needs. However, self-adjustment devices had the best satisfaction rates and consistent use.

Tinnitus (ringing in the ears) is a sound people hear in their ears or head that no one else can hear. It is often described as buzzing, humming, ringing, static, or whooshing. While tinnitus is rarely a serious problem, people should get checked to see if it is related to a medical condition.
