There’s really nothing you can do besides drug up and beast your way through it.
I’ve had ear infections all my life, there is no misery greater than serious infections in both ears. Neither of which respond to anti-biotics, and hearing the doctor say, “I’ll try this one last drug, then we’re going to stick needles into your eardrums”…
Your mission is to get that thing to drain, i used to lay, ear down, on warm wet washcloths. It helps, there are other little things, but since your up and moving it doesnt sound like your condition is too bad.
