I had never in my life fainted or passed out. My blood pressure meds had my pulse down at 40 BPM or so, and I stood up and went into the kitchen for an apple, and the next thing I knew I was on the floor, holding my forehead and bleeding from my like a head-wound can bleed. It looked like a murder scene as my wife came in and started cleaning up blood everywhere.
I put a small towel on the wound to soak up the blood and my wife drove me to the ER for stitches. As I walked into the ER with gray hair and a bloody towel to my forehead, they just opend the door and put my in a bed and I never even had to break stride.
5 stitches, and they kept me overnight. Did lots of tests, and let me go the next day with a clean bill of health. I talked to my doctor and they changed my BP meds to something without beta-blockers. My pulse is higher and no more light headed feelings after I stand up. The amazing thing to me is my only injury was to my forehead, no sore wrists, knees or anything. I guess I did a literal header.
No passing out since.
