Disclaimer - I’m not a doctor. Simply speaking, the vessel in my brain got too close to the nerve, causing me to become almost 100% deaf on one side, the whole thing took 1 day, probably as a result of a stressful day, combined with the overall setup of my brain. The lack of signals coming from the ear is now causing my brain to “hear” the sound based on what is happening in a vein, some false data coming (and also not coming) to the brain, that’s tinnitus. It’s something between the sound of an old tv and the sound they play in movies when a hero gets too close to an explosion.

I had the MRI scan made, and surprisingly the doctor who did it also suffers from that thing. We are both in 30-40 years old range. This helped me to accept it, not going to lie. Like being able to ask somebody who knows what tinnitus is.
