Yes, it is possible to have a reading that high. That reading should have you running to your doctor for treatment. If you can’t get into your doctor within 24 hours then off to either a doc in the box location or your nearest ER. I would think if you told the doctors office what your blood pressure was running, they would either get you in post haste or direct you where to go for treatment. Without treatment bad things will happen to you. Don’t delay in calling your doctor.
If systolic BP is over 185 OR diastolic BP is over 120, you should be in an ambulance to Emergency. Don’t drive — if you have a stroke or heart attack while driving it would delay your arrival and complicate treatment as well as possibly injuring someone else.
