Has anyone experienced this? My father is age 89 in a week. His blood pressure with medication is usually very controlled, but this past Tuesday it got very high. Systolic was 190, I don't remember the diastolic. Heart rate kept jumping around. We went to ER in the first hour the symptoms started presenting. It is two days later. With added medication his blood pressure is still high and he is still feeling dizziness. They wanted to send him home after finding no signs of heart attack or stroke or neurological damage other than unrelated neuropathy, but we asked for an MRI to check his ears and the veins in his neck and to make sure there aren't any bleeds. He isn't nauseated. Neurologist asked him to stand with his feet together and close his eyes, and he was unsteady on his feet when he did that.
