Can a Inner Ear Disorder go unnoticed?

For the past year ive been experiencing severe symptoms of Blurry Darkened vision, Dizziness/spinning sensations[possibly vertigo], daily fatigue, and sleep issues.. Ive noticed that ive been getting tinnitus a bit and ear pains[mostly in right ear]. I have had severly tests over the year including a MRI/CT, and bloodwork for diabeties and hypoglycemia all resulting normal.. If it helps i had to completely cut out alcohol and caffine from my diet[Notice they were major triggers to attacks]. I think it may be something to do with a inner ear disorder, could be wrong though.. Any imput on anything will be helpful..
