Vertigo

Vertigo is the sensation of spinning, and is triggered by a change in position of your head. It may feel like you are spinning, or the world around you is spinning. Other symptoms include the feeling of tilting, swaying, being pulled to one direction, ringing in the ears, jerking, and dizziness. It is often caused by an inner ear problem. Benign Paroxysmal positional vertigo (BPPV) occurs when tiny calcium particles clump up in canals of the inner ear. This interferes with the signals the inner ear sends to the brain about keeping your balance. This may be associated with old age. Vestibular Neuritis is an inner ear problem related to a viral infection. The infection causes inflammation in the inner ear around nerves that are important for helping the body sense balance. In many cases, vertigo disappears without treatment because your brain is able to adapt to the inner ear changes. In extreme cases, Vestibular rehabilitation, a type of physical therapy could help strengthen the vestibular system. Medicine can also be used to relieve symptoms of nausea. For vertigo caused by an infection, antibiotics may reduce the swelling. For less extreme cases it is best to rest and avoid head movements to assure that you wont hurt yourself from falling, at least until the symptoms pass.
