Why do I get ear infections after swimming?
Last updated September 3, 2026.
Because trapped water turns the canal into a bacterial incubator: lingering water wears down the protective wax and skin barrier, and bacteria multiply in the warm moist space - that is swimmer's ear. The pattern: itch and fullness a day or two after swimming, then the tell - pain when the outer ear is tugged. Prevention per CDC: dry ears thoroughly after swimming (tilt, tug the lobe, towel outside only), no cotton swabs, plugs or a cap if prone. The infection itself needs prescription antibiotic drops. Pymander's escalation routing is built and tested specifically for this class of decision; see the safety architecture working paper.
What to do
- Dry ears after every swim: tilt, tug the lobe, towel the outside only.
- Never swab the canal: swabs strip the protective wax barrier.
- Recurrent infections: ask about alcohol-vinegar drying drops - never with tubes or a perforation.
- Get seen if: pain builds after swimming, the ear drains, or hearing muffles - swimmer's ear is treated with prescription drops, not waited out.
