I have a recurring infection in my outer ear - I have had several different types of drops but found lavender oil (stings like buggery) and lots of heat (I use a wheat bag) are the only way to go
But if it isn't your outer ear/ear canal then this won't really work
My mum's GP just told her to put olive oil in hers (inner ear) & I am a bit but it seems to be working
I think you need to see a professional - sorry (GP couldn't get the thingie in my ear it was so swollen last time - I had a boil)
