I had tinnitus for 1 month or so when I was living in London and it went away on its own. Can't remember if it stopped before or after I moved to Germany. In London I was living in a busy area above a grocery shop overlooking a street with a lot of buses going past so there was a constant hum from below. Not sure if it was related but my tinnitus just wouldn't go away. I had had tinnitus before but only for short periods if time and not so intense; only if the environment around me was totally quiet and I was very tired.
