You have high blood pressure if readings average140/90 or higher -- for either number -- though you may still have no symptoms. At 180/110 and higher, you may be having a hypertensive crisis.

Symptoms of a hypertensive crisis can include a severe headache, anxiety, nosebleeds, and feeling short of breath.
