I am 18year old female and have always as long as I can remember had an abnormally high heart rate and blood pressure, for no reason at all. I even stop at those little blood pressure stands in the middle of Wal-Mart and all Ive done is walked around and my heart rate is constantly in the range of 120-140 at all times. It doesnt hurt and I dont notice it day to day, but is this something that could cause problems later down the road for me? Is it something I need to get checked out? Keep in mind I have NO insurance.
