After a knock to the head or a hard stop in a car, most people think first about the head and the neck. Fewer think about the ears. Yet some people notice a change in how sound reaches them in the days that follow: a faint ringing, a muffled feeling as if they are underwater, or a sense of pressure behind one ear. Writing these details down is one of the simplest things you can do before a visit.

This note is educational only. It does not explain what any sound change means, and it is not a diagnosis. Only an examiner who sees you can sort out what is happening. Its purpose is to help you describe your ears clearly, so the appointment covers what you actually noticed.

Why the ears come up at all

The inner ear sits close to bony structures of the skull and to nerves that run through them. Because of that closeness, a head impact can sometimes be connected with sound or balance symptoms, so clinicians often ask about hearing, ringing and fullness as part of a general review. You do not need to know the anatomy to report what you feel. You only need to report it accurately.

What to write down

Start with a plain list. Each entry should answer four questions: what you heard or felt, which ear or whether both, when it began relative to the knock, and whether it comes and goes.

Ringing is the word most people use first. Describe its pitch if you can, such as high, low, or like a hum. Note whether it stays steady or seems to pulse with your heartbeat. Also note whether it changes when you turn your head, lie down, or sit in a quiet room.

Muffled hearing is a separate line. Write down whether speech sounds far away, whether you turn one ear toward people, and whether the TV or phone volume has crept up over the days. A simple daily mark works well: normal, a little off, or clearly harder in a quiet room.

Pressure or fullness gets its own entry. Note whether it feels like a plugged ear, like a change in altitude, or like a tight band. Track whether chewing, yawning or swallowing changes it, and whether lying down eases it.

Keep the record short

A short daily log beats a long memory. Use a notebook or a note on your phone and write one line each morning and one line each evening. Keep the wording plain. 'Left ear ringing, high pitch, louder after coffee' is more useful than 'my hearing feels weird.'

Add how long each episode lasted and what you were doing. Note whether you were in a loud room, on a plane, in a pool, or near a fan or machine. These details help an examiner tell ordinary causes apart from ones that need a closer look.

What to bring and say

Bring the log, a current list of medicines, and any notes from the day of the knock. Say which ear is affected, whether the change is better, the same, or worse, and whether you have had dizziness, drainage from the ear, or any change in balance. Mention any ear problems you had before the knock, since that history matters.

If you have an old hearing test or an earlier ear record, bring it. A comparison is often more useful than a description alone.

Signs that cannot wait

Some signs do not belong on a scheduled visit. Sudden hearing loss, fluid or blood from the ear, a new facial droop, double vision, trouble speaking, a severe or worsening headache, confusion, or repeated vomiting after a head injury need urgent medical care right away. Do not use a log to decide whether these count. Call emergency services or go to the nearest emergency department.

Planning the St. Louis trip

If you are in the St. Louis metro, plan the trip before your week fills up. Choose a time of day when your ears feel most like themselves, arrange a ride or companion if you can, and put your questions on the same page as your log so nothing gets lost in the waiting room. Ask the front desk what to bring and whether the visit is for an ear, a head, or a general review, so you arrive ready.

Keep the note in one place and update it until the appointment. Even a few honest lines, written the same way each day, give an examiner something real to work from.
