This is a good question. It is very important that you make an appointment with your primary care doctor
to have a full history and physical. Depending on what your doctor discovers during your appointment he or she may decide to order imaging such as a CT scan, or refer you to an ear, nose and throat doctor
(ENT doctor). There are many causes for vertigo
(the sensation of the room spinning around you) and dizziness. One of the most common causes of vertigo is BPPV, or benign paroxysmal positional vertigo. It is caused by loose debris in your semicircular canals in your inner ear which causes the sensation of vertigo, especially with changes in position. It can be effectively treated with a series of head movements that your doctor can show you. Other causes of vertigo include vestibular migraine (although usually associated with a headache), Meniere's disease (usually associated with ringing in the ears), and infections such as vestibular neuritis. Again, it is very important to seek medical care as soon as possible to get a correct diagnosis and appropriate treatment to relieve your symptoms. In the meantime, do not drive a car or do anything where a bout of vertigo could cause you to get hurt.
