I have periods of fluctuating BP, where I will have a terrible
headache and head pressure along with nausea. I'll check my BP and it will be like 178/94 with heart rate of 60, and I'll be breathing fast. A couple of hours later, it will be 120/64 with heart rate of 44 and the headache will be almost gone. I'm on three BP meds, Lisinopril 10 mg bid, Coreg .25 bid, and Verapamil 240 bid, which I take faithfully.
