How do you know if you have high blood pressure without going to the doctor to have it checked out? I've been experiencing some symptoms like headache, fatique, and occasional pounding in my ears and I looked them up and it seems like it could be just about every illness, disease or syndrome. I don't have insurance so I can't afford to go to the doctor if it isn't something serious. Does anyone here have high blood pressure and what were your symptoms? Did you have to go to the doctor to get it diagnosed? Did anyone think they had high blood pressure and go to the doctor and it turned out to be something else? What was it? Thanks for your help.
