Over last 3 days it's been fluctuating. I just woke up again feeling funny and I checked it. It's 150/136. I'm watching it but headache is intense. I've taken 20 mg of Bystolic and 100mg of Sertraline for calmness. I don't feel stressed but I do have alot going on. Just wondering if meds don't work when should medical attention become my next option. Other readings have been 165/130, 157/110, 168/138.149/100. Then 129/87, 135/98, 145/88 etc. hope this summarization help you to help me. What reading is high enough to be concerned.
