would not hurt to see a doc but one time high bp's could be from pain or infection. have you had any sinus problems or possible sinus infection? hard to help with little info. i don't see where it says one time high bp.
MAke an appointment to see your doctor...more than BP....no idea what caused one time rise in BP or the other symptoms mentioned.
use olive oil instead of vegetable oil. hope that helps.
Garlic, beets, onion, and etc, V8 juice has all of this but watch out for sodium, fried foods and fatty foods.
if you are not on bp meds already. i would advise you to see a doctor and get some. some bp lowering foods are a good med wheening idea after you get it adjusted with meds. moderate exercise will help also. you definetly want to get checked out so you know if your cholesteral is high or not.
