My blood pressure has been high for 10 hours ten minutes ago it was 150/105 pulse 97 should I go to the ER?

Sure. If you aren't under treatment for hypertension yet... you need to be.

NO. This is not what ERs are for. Those readings aren't bad enough for any emergency. Call your regular doctor for a regular check up.

Your diastolic reading, the lower number, measures the pressure in your arteries between heart beats. Given that your diastolic lower number is 105 I would recommend immediate medical attention if this has been going on for 10 hours. A diastolic lower number of 110 is considered the danger zone.

Yes. I would say ER.

Yes, I agree with Tickle. An ER visit is important with pressures like this. As a nurse I am required to treat systolics (the top number) greater than 160 and diastolics (the bottom number) greater than 100 (which yours is) immediately.
