it didnt start right away but maybe once or twice a week now i get a spike in blood pressure... my head feels like its about to explode i have a mild headache and pounding like my heart is trying to leave my body through my head... it last for a few min. to almost an hour... i monitored my bp it never gets to high but then as quickly as it came it goes away... without warning... what is that? i recently saw my dr. but forgot to tell her... it happened again tonight so i figured id look it up... anyone else goes through this?
