Sinusitis vertigo and dizziness are complications of a sinus infection. Caused by bacteria, a virus, or fungus, sinusitis is inflammation of the sinuses. The sinuses are four hollow cavities in the human skull and are important parts of the immune system as they provide defense against infection. The sinuses are lined with mucous, which expels pollutants and bacteria from the body. It is common for the infection that causes colds to also affect the sinuses and can contribute to dizziness. The dizziness is a result of fluid build-up in the ears that puts pressure on the eardrum and inner ear.
The most common causes of vertigo are inner ear infections or diseases of the ear such as benign paroxysmal positional vertigo (BPPV), vestibular neuritis, and Meniere's disease.BPPV can occur when calcium builds up in canals of the inner ear, causing brief dizziness that lasts from 20 seconds to one minute.It is usually brought on by trauma to the head or by moving the head in certain positions.he most common causes of vertigo are inner ear infections or diseases of the ear such as benign paroxysmal positional vertigo (BPPV), vestibular neuritis, and Meniere's disease.
