My husband has been recently hospitalized for gall bladder surgery and low blood pressure causing dizziness, and blackouts. He was in rehab for 10 days and progressing well strength wise, but still dealing w/low blood pressure readings. Today around 4 pm he appeared disoriented, disturbed, angry, and was slurring his speech. He decided he needed a nap! He is under doctor s care w/an adrenal study scheduled for next week. ???
