My mother was recently hospitalized for extreme high blood pressure (spiking) along with rapid heart rate, dizziness, rapid eye movement, lip twitching that lasted 2 minutes. Doctor stated no stroke, no seizure, blocked carotid artery around 50 to 60 %. Suggested may be a TIA. Happened again tonight. lasted less than 1 minute tonight, no mouth movement. Blood pressure went down quickly. Afterward, she was really tired. What could be happening. She fluctuates between low blood pressure and high blood pressure which has been frustrating for her. She is worried and afraid she is about to have a stroke.
