Is a blood pressure of 108 over 62 too low for a 13 year old ? That is my blood pressure. I quite often get what I can only call migraines where my vision goes blurry and completely unfocused for normally 1/2 an hour if I take paracetemol straight away although I sometimes just have to go to bed because it is so bad. Also somtimes when I standup I black out for a couple of seconds. I wondered if the symptoms are related to my blood pressure. All answers are welcome as this is getting quite annoying. Thanks for reading.
