Re: Deafness/ Hearing loss when turning head to right?
It may not have anything to do with it, but have you considered getting your neck evaluated by a good physiotherapist, preferably one with a strong muscoskeletal background?
I've had this problem off and on for a long time myself, except that I'd experience a temporary loss in hearing whenever bending over or holding my neck in a certain position. I've also experienced frightening spells of sudden vertigo, which seem to happen out of the blue. I consulted several ENT specialists, who didn't seem to find anything out of the ordinary and one even suggested it was vestibular neuronitis which would clear up on its own. But it continued to plague me off and on for years until I finally discovered that the problems could be positional, and went for intensive physiotherapy on my neck. As it turned out, the muscles in my neck and back of my head were so tight that they were causing the occasional vertigo, tinnitus and temporary deafness, not to mention eustachian tube problems while flying, etc! With the help of my physio, I was able to eliminate these symptoms with deep tissue massage etc.
It is worth bearing in mind that not every single physio may agree that muscle disorders/tightness can cause these symptoms, but I can only speak from my personal experience and I am 100% sure they caused mine, so it's worth investigating if it might be at all relevant to you. I hope this helps.
