Hello! Welcome and thank you for asking on Chat Doctor ! Your symptoms could be related to low blood pressure or orthostatic hypotension. An inner ear disorder can not be excluded too, considering the dizzy spells. For this reason, I would recommend first consulting with an ENT specialist for a physical check up and labyrinthine tests. Other tests to consider would be a Head Up Tilt test for orthostatic hypotension, especially if your blood pressure values Chat Doctor.  Hope you will find this answer helpful! Best wishes,
