Should I be worried about a blood pressure of 115 over 59?
If there are no symptoms associated with this and this is your regular BP level then you need not worry about this.
If there has been sudden fall in BP level, then this should be brought to notice of your doctor sooner.You might need modification in dosage of BP medications, if you are taking any such medication.
You need to watch on symptoms like headache,dizziness, disorientation or imbalance etc. In case of any such symptoms you will have to bring this to notice of your doctor.
Please ask if there are doubts.Regards.
