Hi, my name is tina, lately i have been having problems with my legs giving out on me and they feel numb and tingly, i have also been having a headache and blurred vision with dizziness and lightheadedness. i am currently taking meds for high blood pressure. this past week i had to go to the emergency room for these symptoms, they did a ct scan for stroke and said it came back normal. on my follow up with my primary doc she ordered a mri and lab tests, i found out today that every thing was normal. i dont understand this, if everything is coming back normal why am i still having these symptoms???
