What's Wrong With My Ear?

I have this pressure build up in my ear and it hurts to even touch it, mainly right behind it lower to my jaw. It slowly builds and then goes, but it's extremely painful. Has anyone had a similar experience? And before you say "go to a doctor" I don't have fucking money to go to a doctor. I live in America where shitty healthcare is the standard. It's like $100-150 I don't have right now. I have to know what I can do at home first.

Hey guys turns out it was just a dog hair that had gotten trapped in my ear! Glad it wasn't an infection or anything and that I didn't have to pay $10000 just for them pick a dog hair out.
