Not sure anything but antibiotics will work to fix an ear infection.

I use hydrogen peroxide for colds & ear infections https://www.naturalnews.com/025125.html

I heard about a child who continuously got ear infections. They even did scans to ensure it wasn’t an inner ear infection as that section cannot be viewed with ear equipment. His Mum decided to take him off dairy food ( he ate a lot of it) and he got very few infections after that.
I get sharp “stabbing” pain (mainly in my right ear) occasionally – mainly during Spring or very dusty weather. They came to the conclusion that it was an allergy. I used special ear drops for a week or so and that helped when it was really painful.

Just time… Not much actually helps, natural or otherwise.

I would go see your GP for advice especially as its the Ears there is nothing more painful then a ear ache or infection

My mum always used a warm wet towel for us

There are many herbs you can use, but you need to use another search engine than google, because google is stopping a lot of searches with the word natural remedies in the search. Try duckduckgo.
Here is one idea:
Ginger. Ginger has natural anti-inflammatory properties that can help soothe pain from earaches. Apply ginger juice, or strained oil that was warmed with ginger in it, around the outer ear canal. Do not put it directly into the ear.
and another one:
Onion:Heat an onion in the microwave for a minute or two. Then, strain the liquid and apply several drops to the ear. A person may want to lie down for 10 minutes, and then allow the liquid to flow out of the ear. Repeat this as needed.
Massage helps, and hold a warm cloth to your ear.
Also drink celery juice which will clear out the infection, must be pure celery without the fiber so strain it and drink on an empty stomach and not eat or drink anything for at least 15-30 minutes to allow it to work.

I always remember my mum putting warm olive oil drops in my ears when I was young, and a warm compress for pain.
