People who say they feel 'dizzy' are usually referring to a sensation of turning round or whirling. Alternatively, dizziness may be used to describe a swaying sensation, or a feeling of weakness, faintness, light-headedness or unsteadiness. Occasionally, some individuals say they have blurred vision, feelings of unreality, faints, blackouts or even epileptic fits. All these are sometimes referred to as 'dizzy spells'There are many causes of dizziness. Conditions that affect the inner ear may cause this symptom, because this is where the organ of balance (the labyrinth) is situated; more rarely, conditions that affect the brain may also lead to dizziness. Abnormalities of heart rhythm or falls in blood pressure when standing up may cause the sensation of light-headedness. The most common conditions to affect the inner ear and cause dizziness include Meniere's disease, 'benign positional vertigo' and 'vestibular neuronitis', which is also known as 'viral labyrinthitis' and may result from a viral infection of the labyrinth.
The exact symptoms depend on the actual cause of the dizziness. Patients who have Meniere's disease describe recurrent, severe attacks of rotational dizziness (the feeling of whirling), known as 'vertigo', and deafness and ringing in the ears. These attacks come on suddenly and can last for minutes to an hour or longer. They are usually so severe that the person cannot stand or walk and may have nausea and vomiting. There may also be a feeling of fullness in the ear. The attacks may occur several times a week for many weeks on end, or they may disappear on their own for several years.
Benign positional vertigo is another problem of the inner ear. Episodes of rotational dizziness are triggered when the person's head is moved into specific positions. It usually occurs when lying down in bed or when the head is tilted backwards. Occasionally, a sudden turn of the person's head triggers vertigo for a few seconds. This condition is more common in elderly people.
Viral labyrinthitis is a condition that occurs mostly in young adults, although children and older people may be affected. It is often preceded by a cold or flu-like illness when a sensation of being top heavy or off balance may be felt. There is a sudden onset of severe vertigo, nausea, vomiting and the need to remain still. Symptoms usually last for hours, although they may occasionally last for several days. This condition is thought to be caused by a viral infection of the labyrinth.
Very rarely, tumours affecting the nerve that supplies the inner ear may cause dizziness. This condition is almost always associated with deafness in the affected ear.
Dizziness is a common complaint of people who suffer from migraine (see separate Factsheet).
Rotational dizziness in elderly people may result from interruption of the blood supply to the base of the brain. It is rare, however, for this condition to cause dizziness alone and there are usually other symptoms of disturbed brain function. Very rarely, multiple sclerosis may cause rotational dizziness in young adults. However, other symptoms of this condition are usually also present.

The reason for your dizziness depends on several different things,when are you dizzy? Is there a certain activity or movement that brings the dizziness on? Is the dizziness accompanied by any other symptoms such as ringing or roaring in the ears? Any Nausea or vomiting?
Sudden changes in position say from a sitting to standing position can cause a drop in blood pressure which causes dizziness. Avoid sudden position changes remembering to get up slowly. Have someone (your Dr. or nurse) check your BP lying,sitting and standing to assess for this condition. Vertigo is usually treated with medications such as antivert and requires a RX by your MD. If the dizziness continues and is effecting your daily living return to your physician and request further test to determine the cause.

Dizziness can be caused by many things, some more serious than others. For example, middle ear infections often cause vertigo. Low blood pressure, lack of sleep, dehydration, glaucoma of the eyes, low blood volume and reactions to certain medications can cause dizziness. The most serious of these causes are dizziness caused by heart arrythmias, low blood volume, low blood pressures and infections of the spinal cord and brain ( meningitis) However, since you have been experiencing this three months, it is not likely to be a spinal cord/brain infection that is usually fatal much sooner than 3 months and diagnosable by blood testing. If your general medical practitioner cannot diagnose it, you should visit a cardiologist or an EENT specialist for a more thorough and specified examination.

Dizziness is a common and inclusive term for several specific symptoms which include pre-syncope, disequilibrium and vertigo. Pre-syncope is a faint, lightheaded sensation often experienced with rapid standing. Disequilibrium is an off balance, tilting or falling sensation not accompanied by nausea. Vertigo is a room spinning sensation associated with intense nausea and sometimes vomiting. Each of these more specific words is encompassed in the general term dizziness. Pathologic causes of dizziness can be related to the ear, eye, heart, respiratory system or central nervous system.
Neurological dizziness is not due to spinning around, standing upside-down or motion sickness. It is a light-headed sensation in which there is a head-ache and reduced consciousness. This can be accompanied by seeing stars, blacking out, convulsions, fainting, paralysis and other neurological symptoms. Take note that the dizziness caused by fainting is different from that of dizziness caused by spinning too fast. It is a different sensation. The stars (white spots that appear to move infront of the eyes), convulsions and confusion are often the result of excessive neuronal discharges often caused by the chemical glutamate. Oxygen deprivation can result in excessive neurological discharge leading to brain damage or/and convulsions due to glutamate after prolonged periods or about minute.

Dizziness may be caused by low blood pressure or by high blood pressure, as well as by low blood iron level. You might have a problem with your eyes; this can cause also dizziness. Anyway, a blood exam will tell your doctor the right answer. I wish you to be healthy again.

get a second opinion. Keep going to doctors until they can figure it out.
