No, I'm not talking about the movie. I recently had a MRI done and it showed a few lesions on the brain. I have some symptoms of multiple sclerosis which correspond with the lesions, all on the left side of the brain and symptoms on the right side, mainly in the legs. Anyways, the neurologist ordered a spinal tap for me and it is to be done Thursday. I was wondering if any of you have had one, and if so is it painful?
