It is the feeling that oneself or one's surroundings are spinning. Vertigo, contrary to popular belief, is not the name of a disease, it just means dizziness. Dizziness is often caused by an inner ear problem. Some people describe their balance problems with words such as "feeling dizzy, feeling shaky, floor slipping, inability to stand, feeling like falling, being pulled to and fro". Feeling unstable and wobbly without a spinning sensation can also be caused by an inner ear problem.
Ear diseases also often cause dizziness. Especially middle ear infections, inner ear infections, "Benign Paroxysmal Positional Vertigo", which is called the shift of crystals in the inner ear, Menierre's Disease and Vestibular Neuronitis are common causes of dizziness.
