even though the doctor says the flu injection can't cause blood pressure to rise i had my second ever flu jab last week and within a few hours i started to feel nauseous and light headed. by the next morning i felt much worse. i had an oral hygienist appt and decided i'd probably be ok to attend. after that appt i was feeling so dizzy i went into doctors room in the same building to get checked as didn't think i could safely drive home. it turned out my bp was highish at 170/80 and had dropped to 144/90 an hour later. the doctor couldn't find any cause for the raised bp. i am 65 in very good health not on any medication have never had high bp before. i am sure it was the injection that caused it. i came right by the end of the second day. i will never have another flu injection.
can getting the flu shot raise blood pressure? . i have been monitoring my blood pressure for about 3 weeks now and the readings have been normal (110/75) but i noticed ever since i received my flu shot from a few days ago my blood pressure has been reading higher (140-150 range/85). is this a side effect of the flu shot?
