Thanks for replying. Can I ask how you feel about the possibility of not having been diagnosed as quickly if your LP came back negative?

A girlfriend of mine has numbness/tingling on one side, arm and leg it was so bad she went to the ER. She has one lesion in her brain but they did a spinal MRI and it was clear so now she doesn't think she has MS. Blood work is clear and there isn't any sign of a stroke or cardiac issues. They are going to do a spinal tap but it sure sounds like MS to me so I was just wondering if people routinely get diagnosed with only 1 lesion.

Unfortunately, or fortunately, I had a whole head full of the buggers so my dx wasn't a problem, no LP needed.
