Hi my mother is 56 years old and she has got high blood pressure, she is currently on medication for it. I took her to ER yesterday she is having real bad headaches, her whole right side of her face in tingly she said, they did blood work and ct scan of her head, and a ct scan with contrast of her neck, urine sample, chest x-ray, EKG and they said that everything came back fine. She is real dizzy, and her blood pressure has been running around 155/99 which i know as a nurse that is to high. she does smoke and has smoked for about 40 years, but she dont smoke a pack a day. They diagnosed her with vertigo, but i dont beleive that is all that is wrong with her, could someone please help me?

### output:

Hello! Welcome and thank you for asking on Chat Doctor! I read carefully your question and understand your concern. As her brain CT scan has resulted normal, possible brain ischemia or hemorrhage have been excluded. High blood pressure could be the cause of persistent headache. I would recommend performing a brain MRI to detect possible brain ischemic events (which are not detected by the CT scan) and a Doppler ultrasound of the cervical vessels to examine the blood flow in her cervical arteries to investigate for possible vessel narrowing, which could lead to vertigo. Meanwhile, I would recommend discussing with her attending physician to make the proper changes to her actual antihypertensive therapy in order to have a better control of high blood pressure. I would also recommend taking aspirin 80 mg, to prevent possible brain ischemia (which could be related to the vertigo and tingling face). Hope to have been helpful! Best wishes,
