Hi. My dad had an angioplasty 3 years ago and still takes his maintenance medications today. He s about 6 ft tall, has a big tummy, around 40-42 inches of waistline. last night he experienced some dizziness while driving, and when he got out of the car started vomiting. He threw up about twice last night and then two more this morning when he woke up. he said he felt dizzy when he opened his eyes as he woke up. We got him to a doctor, they said it was just vertigo. I asked a neurosurgeon about it, and she said it might be cerebellar stroke.What could be your diagnosis for this?
