I understand your concerns. How old are you? Do you have any other medical conditions? Do you take any medications?
Your dizzy spells could be secondary to different etiologies including cardiac, neurological and volume status. Conditions like abnormal cardiac function, stroke or dehydration can cause dizziness. A full evaluation including a CT scan of the head, carotid doppler, MRI of the head, echocardiogram and pacemaker interrogation needs to be done. Depending on the results further workup can be ordered. Let me know if you have any other questions.
