Two years ago I had a severe dizzy spell and was sure I was going to pass out. At the time I was home alone so I called 911 and was taken to the hospital. I told the ER doctor I have CFS and I get dizzy alot whne I stand for a while, exercise or mentally exert myself for a long time. I also told him a headache acompanies these symptoms and only laying down and not concentrating on anything makes them better. He ordered a CT scan as these were nuerological symptoms. The scan came back normal. I have never had an MRI of my brain only the CT scan. IS one better than the other? Are CT scans usually normal in CFS patients? Sometimes I feel my symptoms are so nuerological especially when I exhert myself. How can I have a normal CT when I feel like CFS is messing with my brain?
