Vertigo or dizziness is the name given tpo the moving sensation whihc in most cases is a spinning movement. This sensation or dizziness may cause nausea.

Symptoms : A spinning sensation. When this sensation occurs together with an unbearable buzzing in the ears, it is called Meniere Syndrome and is produced by a gradual accumulation of fluid in the inner ear. This Meniere disorder may cause the loss of hearing with time. Only a physician can correctly diagnose this disorder.

Causes : When this spinning or dizzy sensation occurs occasionally, itm ay be due to several factors, like : Too much alcohol, riding on a bus or plane with a lot of movement, a blow on the head, etc.
When dizziness occurs frequently, causes may be from a problem in a part of the inner ear which is called the semi-circular canals where receptacles filled with pilose cells (hair shaped) are found. These hairs detect the movement caused by small crystals in the canals which flow over them.

When these small crystals come to rest in another part of this hairy canal ,with the slightest movement, they will provoke by means of pressure an arroneous message to be transmitted to the brain concerning the position of the head, which will cause dizziness.

If you wake up the next morning feeling like your head is going to explode after a night of drinking too much alcohol, then it termed as a Hangover.
