Hello and hope you are doing well.
Benign paroxysmal positional vertigo (BPPV), is an entity in which with movement of the head the person is likely to get dizziness. This happens because of a disorder of the labyrinth system in the inner ear. It can get affected due to head injuries, surgeries, nerve inflammations and as a side effect to medications. In a majority of cases the cause is not known. It is diagnosed by a physical examination and sometimes blood tests, a CT and MRI and audiology tests can further help with diagnosis. Therapy is with diazepam and OTC meclizine. Other measures which help are elevating the head end of the bed, drinking plenty of fluids, avoiding sudden movements of the head and taking precautions with driving during an attack. If your symptoms worsen, please consult your doctor for an evaluation.
Hope this helped and do keep us posted.
I am not a doctor, but it could be BPPV. You could try some Meclizine 25 mg. (Dramamine, over the counter), and see if it helps. Also, you could go online and check out the Epley Maneuver and try doing the exercises for "at Home". You can ryt some Brandt/Daroff exercises, or something like that also. Hope you feel better.
