I am a 31 year old female. For the past 2 years, I have experienced stroke like symptoms, numbness on one side of my body from my arm down to my leg, slurred speech, difficulty talking, thinking, and understanding words. I had problems moving my arms and walking. I literally had to think and figure out how to do simple tasks such as chewing and moving my limbs. I went to the ER and MRI and CT scans were normal. I did not have a stroke or TIA. Another time I went to the ER they admitted me and did a MRI with contrast and that showed normal as well. I went to a neuro and they prescribed Vitamin D. I went to a cardio and heart looks normal. I also have frequent migraines and have high blood pressure. I just experienced another episode (my 6th one) a few weeks ago. What could this be?
