I was wondering if my blood pressure is something to be worried about. I have been taking it for the past week or so and it has been ranging from around 86/44 to 92/58. I am sometimes dizzy and lightheaded when standing (I have sort of blacked out for a second and had to grab the wall. That was a while ago, though). I also have sort of poor circulation (cold feet and hands). Is this something to worry about and ask my doctor or is it something normal?
