i've forgotten what it's like to hear out of my left ear. for the past week/week and a half, i've felt unbalanced and all sounds going to my left ear have been muffled. this could be caused by damage to the cochlea's hair cell receptors or problems with the system that conducts sound waves to the cochlea. i hope it's neither. i've tried yawning, cleaning my ears, and just everything to get the full use of my ear back. but nothing works. this was written a long time ago but i forgot about it. i think i have complete hearing in both my ears now.
