In brief
If hearing difficulties affect daily life, contact a healthcare centre or hearing service for an assessment. You do not need to wait for a self-test result.
What it can mean in daily life
In Sweden, 1177 advises that sudden hearing loss in one ear should be assessed by a healthcare centre or out-of-hours clinic as soon as possible. If closed, you can wait until it opens the next day. Call 1177 for healthcare advice.
Next steps
It can help to note when the change began, whether it affects one or both ears and which situations are difficult.
