Okay, here's my update on what's been going on...
Went to the ER yesterday and after spending 3 hours in the waiting room listening to kids cry and scream I finally got to see the doctor. He ran a couple of basic hearing tests, but all I could hear with my left ear was a tuning fork. He referenced me to go to a ENT today, which I just got back from.
I had a couple auditory tests taken where they compared my two ears on hearing ability and word comprehension. Right ear - 100% on both. Left ear - scored a 28% on word comprehension and found that my left ear is basically tone deaf for the majority of auditory frequencies.
This is kind of life-changing news for me. I am an Army cadet and won't be able to receive a commission unless I can pass the hearing test, and at this rate it doesn't look like I will be able to even with the drugs I have been prescribed, and from everything I've heard it's near impossible to get a waiver for hearing.
Guess I should've worn ear muffs.
