no elevated blood pressure is not a known side effect of the flu vaccine. other things such as pain can cause your blood pressure to rise. if your blood pressure doesn't return to normal in the next couple of days have your doctor check it out.
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?
