ive had these for years (even before my pots). they started getting worse after my pots and after i started meds that caused brain zaps. my doctors have suggested it could be a blood rush, brain zaps, or something else entirely. ive noticed if they happen A LOT, laying down without lights and a cold compress on the neck CAN help, but ofc this is j my experience
