Can you use a spinal tap that was previously done? I had one done in Feb. 2005 when I was being tested for MS, I also have Lupus. I really don't want another one cause I had such a horrible reaction and after 4 days of Pain, had to have the blood patch. My mother has Alzheimer's and her sister died of it. I am fearful I might be getting signs and heard you can look at the spinal fluid to detect early signs. Please let me know.

Thanks, LeAnn Bitler
