Meniere’s disease
Tinnitus can be a sign of impending Meniere’s disease. If you experience hearing loss and tinnitus, pay attention. If it is Meniere’s disease, you’ll start getting vertigo and the world will spin around you for 20 minutes to 24 hours. You may be very nauseated. Eventually, untreated Meniere’s will cause permanent hearing loss.
Meniere’s is caused by too much fluid in the inner ear. The causes are unclear but are linked to a blockage, infection or abnormal immune response.
Malformation of Capillaries
Arteriovenous malformation (AVM) is a fairly rare condition with unknown causes. Basically, arteries within the brain connect to the veins without traveling first through capillaries. AVMs can rupture, hemorrhage, and reduce blood flow to the brain. Occasionally, it can lead to an aneurysm. The condition occurs in utero and often exbibits symptoms between the ages of 15 and 20.
Along with tinnitus, you may have hearing loss on one side and facial numbness. It generally can be treated.
