I had something similar in my ear for almost a month earlier this year. It would only bother me when I breathed certain ways, or moved my jaw in some locations. When it did bother me though, it was hell. Felt like I had water in my ear and someone was poking my eardrum with a twig. It would even wake me up in the middle of the night on some bad nights. I kept trying to get it out with Qtips, peroxide, Murine ear cleaner, snake oil, nothing worked. Finally I took a day off work and did a walk in at the doctor's office. There was a small hair in my ear, pressed flat against my ear drum and stuck between the top and bottom of my ear canal. It was pretty much wedged in there. It was from a hair cut I had gotten right around when the problem started.
So, the doctors breaks out this _massive_ syringe and start flashing my ear with distilled water for a few minutes. Eventually, the hair came out. I felt SO much better one it was out of there. Only problem then was that I had no balance after the water jets from the syringe blasted my ear drum. I fell into a wall at the doctor's office, and all the nurses thought I passed out and hurt myself. Very embarassing 😀
