This disorder of the inner ear is known as Meniere's disease. It can cause severe dizziness, a roaring sound in your ears called tinnitus, hearing loss that comes and goes and the feeling of ear pressure or pain. It usually affects just one ear. It is a common cause of hearing loss. Attacks of dizziness may come on suddenly or after a short period of tinnitus or muffled hearing. These attacks vary from person to person. Some people have single attacks of dizziness once, while others may have many attacks close together over several days. Some people with Meniere's disease have ‘drop attacks’ during which the dizziness is so bad they lose their balance and fall. Scientists don't yet know the cause. They think that it has to do with the fluid levels or the mixing of fluids in the canals of your inner ear. Doctors diagnose it based on a physical exam and your symptoms. A hearing test can check to see how it has affected your hearing.

Your doctor will do Neurological Evaluation where he will ask questions about your symptoms and ask you to describe what happens when you have an attack. Your doctor will want to rule out other ear problems, so he or she may do some tests. These tests might include hearing and blood tests, an MRI or CT scan or special tests that check your balance and how well your ears work. Treatments include medicines to control dizziness, limiting salt in your diet, and taking water pills. A device that fits into the outer ear and delivers air pulses to the middle ear can help. Severe cases may require surgery. This is how Meniere’s disease is dealt with, helping the patients achieve a better living.

Migraines are a form of a vascular headache, which means it is related to functionality of blood vessels. Migraine headaches are caused by a combination of vasodilatation (enlargement of blood vessels) and the release of chemicals from nerve fibers that coil around the blood vessels. It is the enlargement of these blood vessels which cause the severe headaches and dizziness. In the course of a migraine, the temporal artery enlarges. This is the artery that lies on the outside of the skull bone right under the temple of the fore head. This enlargement causes a certain scratching or an itch in the surrounding nerves and causes them to release come chemicals, which in turn cause inflammation and pain.

This inflammation often happens periodically to those who suffer from migraine headaches. It can happen on one or both or either sides of your head. Migraine headaches are often accompanied with mild or aggressive dizziness which causes nausea and urge to throw up. The reason or causes of migraine headaches can be anything to everything and they vary in a large number. The most common causes of migraine headaches occurring in people are increased sensitivity of the eyes to light (photophobia) with visual disturbance and flashes (aura), increased sensitivity to sound (phonophobia), dizziness, blurred vision, cognitive disturbances, and other increased periods of exposure to anything that might desensitivise the cranial nerves.
