I take Lisinopril 5mg daily. My HBP has been consistently around 180/97. Head hurts, I can feel my chest sharp pangs shooting through. I've had a 100% blockage in my LAD on one branch, and around the bend to the other artery that goes down was two years ago over 90% blocked I've took another 5 mgs of lisinopril to no avail. Then I thought my blockage was causing it. I also was in a 3 to 5 day Klonopin withdrawal as I ran out. Don't know how but I did. So I took one nitro glycerine as I had some angina and then finally my blood pressure dropped 60 points on both sides. Down to around 137 0ver 74. Blockage if you ask me. What do you think?
