How come there is an excessive of fluid in the inner ear? where are those fluid come from? sweat entering the ear ? :))

Meniere's?: If you are referring to the cause of meniere's, the problem is in the transport of salt on a molecular level. When there is improper transport of salt ion's, the fluid follow the salt. This causes excessive fluid in your inner ear. (it isnt caused by sweat that goes from your outer ear into your inner year). This is the reason that the first line of therapy is to keep your salt intake low!
