Seek medical care. You should see a doctor. If your blood pressure is causing neurologic symptoms, it is a hypertensive emergency and is treated as such - emergently.
Bad blood pressure . You need to get your blood pressure under control. You need to see your doctor right away to have medication adjusted. You may need blood work or an ultrasound of your kidneys to rule out renal artery stenosis. In the meantime you need to minimize your salt intake and avoid Ibuprofen and Naproxen since they can cause your blood pressure to go higher. Go to the er if your symptoms worsen.
