### Patient: Hi Doctor, I have been experiencing dizziness, vertigo, and difficulty in seeing, especially when I move my head. Sometimes, I have double vision too.
### Doctor: Based on your symptoms, it seems like you might be suffering from vertebrobasilar insufficiency. To be sure, we will need to perform a few tests. You will need to undergo a Radiographic imaging procedure, Complete blood count (CBC), Electrocardiogram, Glucose measurement (Glucose level), X-ray computed tomography (CT scan), Ultrasonography (Ultrasound), and Cardiac enzymes measurement (Cardiac enzymes test). These tests will help us evaluate your blood flow and detect any underlying abnormalities that may be causing your symptoms.
