About a month ago, I had a bout of vertigo; however, ever since that time, I have not felt normal - frequently feeling unstable. A couple of days ago I had another bout of dizziness. When I got home, I think I had an anxiety attack (heart palpitating, head pounding, I felt like I was going to faint). After walking around the house, my heart calmed down. I went to see my doctor. He took blood tests on me which was normal. I just got through with an MRI which the results will be in tomorrow. I am experiencing vision changes as well, and my eyes get tired very easily.
