Hi. I understand bp concerns. I have them too. I was borderline and highly anxious because of that for a few years. FINALLY, my doctor said enough and prescribed Losartin for me which dropped my bp 30 points.
You are over checking your bp. This looks to be highly anxiety related. I understand it. I was there. You gotta pull back and consider treating your anxiety. Talk therapy for health anxiety, medication? these things CAN help.
Taking bp at home can be unreliable. I bought a very expensive cuff but still. It's not like the doctor's office. You've been to a cardiologist and had a clean bill of heart health. Now, focus on the other things. Don't drink alcohol and if okay by doctor, begin a solid heart healthy diet and exercise routine. Get plenty of sleep. Treat your anxiety professionally.
If your bp is going up and staying up? Talk to your doctor about another blood pressure medication. I will tell you that I am not consistent in the normal range and I feel better. I so didn't want medication for some reason. But? My genetics didn't cooperate or my love of cheese cake. Oddly, since I started the Angiotensin 2 blocker, I've also lost weight. That same hormone that creates the bp issues also makes someone hang onto weight more easily. I'm glad I treated my genetic blood pressure issue.
This is kind of strong advice. But you are really struggly. PVC's are indeed normal and often the effect of anxiety. They monitored for these. Doctors are trying to give you care. Try to trust them.
