Do you know any home remedies for ear infection?

Simple version: I don’t have health insurance, so I’m asking for at home remedies. I have an ear infection in both ears.

Complicated version:
Before my health insurance went up, my primary linked the ear infections to an allergic reaction I was having to a cat shelter and something about being in a plane making it worse… I volunteered at a cat shelter with 140 cats for two days before I couldn’t handle it anymore. I’ve always had short hair cats and never showed allergies but being in a shelter with so many at once overloaded my system. Shortly after the shelter work, I adopted a medium hair kitten.
My assumption is that my body just hasn’t gotten over the initial reaction because of constant exposure to my longer hair kitten. I am hoping that I am not allergic to medium hair cats. (For those who may be concerned, the symptoms aren’t bad enough for me to consider giving him up. That’s not an issue here.)

Symptoms:
Initial symptoms were pretty bad: hard sneezing, coughing, trouble breathing. After 6 weeks, those calmed down to what I have now.
Current symptoms are just itchy eyes, ear infections, and occasional sneezing.
