How do I know it is the outer ear?
Pull gently on your earlobe, or press the small flap in front of the ear canal. If that is painful, it is otitis externa. A middle ear infection does not hurt when you move the ear — which is a simple and reliable way to tell them apart, and it changes the treatment completely.
Why do I keep getting it?
Most often because of cleaning. Cotton buds remove the protective wax and scratch the canal skin, which is exactly how bacteria get in — so the effort to keep ears clean is what causes the infection. Water retained after swimming is the other main reason. Stopping all cleaning, and using acidifying drops after swimming, prevents most recurrences.
Why are the drops not working?
Usually one of three reasons. The canal is too swollen for them to get in — which needs a wick inserting. They are running straight back out because you are not lying with the ear uppermost for five minutes. Or after repeated antibiotic courses, the infection has become fungal, which needs different treatment and usually cleaning of the canal.
Do I need antibiotic tablets?
No, for ordinary otitis externa. Oral antibiotics do not reach the ear canal well and are not the treatment — drops applied directly are. Tablets are reserved for infection spreading beyond the canal or for people who are immunosuppressed.
Can I go swimming?
Not during an episode — water sustains the infection, and this is one of the commonest reasons treatment fails. Once it has settled, use well-fitting earplugs, dry the ears thoroughly afterwards, and consider acidifying drops after each swim if you are prone to it.
How do I get the drops in properly?
Warm the bottle in your hand first, lie down with the affected ear uppermost, put the drops in, then stay lying there for a full five minutes. Pulling the ear gently up and back straightens the canal and helps them reach further. Almost everyone skips the five minutes, and the drops simply run out.
I have diabetes. Does that change things?
Yes, significantly. Severe or persistent ear pain in someone with diabetes needs prompt assessment rather than another course of drops, because infection can spread into the surrounding bone. Pain that is unrelenting, worse at night, or accompanied by any facial weakness needs urgent hospital review — and the outcome depends on catching it early.
My ear is really itchy but not very painful.
That pattern suggests either a fungal infection — particularly after repeated antibiotic drops — or an underlying skin condition such as eczema or psoriasis affecting the canal. Both need different treatment from a bacterial infection, and scratching to relieve the itch is what keeps it going.
