I've had it for years and it's getting worse.
I have three or four different noises competing to be the dominant noise.
There is a high pitched whine, a whooshing throbbing noise like being in the bowls of a ships engine, a very fast metallic knock that is very similar to a noise I heard when a stone got stuck in the wheels of the car. I also have an odd noise in my left ear that gets louder and louder when there is loud ambient noise.
It is worse at night when all around is quiet.
I wouldn't wish it on anyone but on a personal level, although it does interfere with sleep and coupled with deafness does make hearing difficult at times, I am used to it lol
