I have a problem with one ear that is called endolymphatic
hydrops, which is something like Meniere's without a severe
hearing loss. Apparently the fluid in the semicircular canals
responds to changes in body fluid levels - which it isn't
supposed to do- and sends messages to say you are dizzy. I have
spontaneous vertigo attacks and motion induced dizziness - all
lasting only a short time. Well, what does this have to do with
tinnitus? I also have tinnitus in that ear, which is helped by
some things I have been taught to do for dizziness. Eating small
meals several times a day keeps your body fluid levels fairly
consistent. Also avoid salt. That really makes a difference with
tinnitus and avoid too much sugar as well. Other things to be
careful of are fatigue and dehydration. All these things have
been helpful for me.
