Your diastolic pressure of 126 is quite high actually. That is sort of like the pressure that is still maintained when you heart is a rest. Systolic ( the top number) can cause damage for sure....but a high diastolic pressure can really havoc on your body. I hope you are monitoring your blood pressure to see if maybe that was just a fluke or if your diastolic pressure is that high all the time. If it is...I would certainly have it checked by your doctor.
