I just found out this past summer i have High BP. I was waking up everyday for about a month and my vision was blurry almost like a double vision it would take about 10min for it to correct itself. I also had constant headaches, but aside from that i had no effects.
I went into work one day and just about got sick, couldn't concentrate and was figity. I almost passed out, our Medic transported me to the hosp and did abunch of bloodwork, CT scan, etc etc. Turns out my BP was 168/120. I followed up w/ my family doc and since being put on 2 meds my headaches/ vision problems are gone. I try to monitor my BP and watch what i eat (dosen't always happen). I'm learning to eat more veggies, and trying to use less salt. Sea Salt is a good option if you need salt.
But excersise, eating better and watching your sodium intake will do wonder's. I was actually surprised how many people have high BP.
