Blocked ear after swimming: could wax be involved?

Earwax normally protects the ear canal, but a compacted plug can prevent water from draining and make the ear feel full. You may notice muffled hearing, pressure, itching or ringing. Water exposure can also irritate the canal, and pain, tenderness, discharge or pain when touching the outer ear may point to inflammation rather than wax alone. A blocked sensation does not identify the cause by itself, so an examination is useful if it does not settle.

Keep the ear dry and tilt your head to let surface water escape. Dry the outer ear with a towel; do not put cotton buds, fingers, hairpins or ear candles into the canal. If you have no ear surgery, a hole in the eardrum, ear discharge or significant pain, a pharmacist may advise wax-softening drops. Follow the product instructions. Do not force water into the ear. If hearing remains muffled, a clinician can check the canal and discuss ear wax removal.

Seek prompt care for severe earache, fever, pus or blood, sudden hearing loss, dizziness, facial weakness or swelling around the ear. Arrange an assessment when blockage persists, recurs after swimming or affects hearing, because wax and canal inflammation need different treatment.

Ask whether the canal contains wax or signs of irritation, whether drops are suitable for your eardrum, and whether you need a hearing test after the ear is clear.
