I am having a lumbar puncture to rule out MS. I have a diagnosis of Transverse Myelitis (TM) which can go on and develop into MS. The TM has caused the neuropathic pain (which I still have) and loss of bladder function (which is almost fully recovered). I have already had brain and spine MRIs.

My neurologist wants to be sure that there is no ongoing inflammation. I would therefore venture the opinion that if central nervous system involvement is a possibility then a lumbar puncture would be a necessary test.
