It began as a sharp pain in the left ear along with big difficulties equalizing the pressure in the ear (and when I was very forceful, I'd hear crackling noises in the ear) and hearing loss. 2 days later, I noticed that I felt slight dizziness and I had got the usual ringing tinnitus where it sounds like an old TV in the left ear. This day, I went to see a doctor to be told the eardrum and the area around it was a bit red. At this time, the pain was completely gone, had no problems pressure equalizing and I had retained a bit of the hearig, but the tinnitus and dizziness was still there. I started using the eardrops, but it had no kind of effects at all and quit using it on day 4. At this time, the hearing was completely recovered, but still I had the dizziness and noises in the ear.
I waited 2 weeks before my next visit to the doctor, and he told me that I had a slight barotrauma. However, I knew that was not the case, so 2 days later I went to see a specialist. She checked my ear, cleaned it, checked my vision etc. etc. I got the reply that there was nothing wrong with my ear and was forwarded the the neurological division. They made some tests and took bloodsamples and also CTed my brain to see if there were any problems there. The results came out NOTHING.
I am in a high doubt that there isn't anything wrong. The dizziness and tinnitus came along with my ear problems, so it would be more logical thinking it has caused some kind of damage. I can also say that I've noticed that no earwax is coming from the left ear ever since, and no mucus is coming out from my nose, especially not from the left nostril. I have to be VERY VERY forceful when blowing my nose and keep doing so for about 10 minutes to get a BIG MASS of jelly-like mucus from the nose.
