Hi, I'm Dr.Nitika-a board certified physician. Welcome to JustAnswer. I'm reviewing your question now, and will post back with your reply ASAP.
As per your description,your blood pressure is very high.
And you should take your anti-hypertensive medicine now if you are taking.
Let me know which medicines are you taking.
In most of the cases, blood pressure above 180/120 mm Hg is considered emergency hypertension and we recommend to seek an urgent medical attention at ER.
There can be associated symptoms like headache,lightheadedness,dizziness,confusion with high blood pressure.
You should take OTC Aspirin.
If you don't have medicines along with you then don't wait and visit ER to prevent any complications like heart attack,stroke.
