Hi I had a LP done and it was clear. PPMS. Spinal cord inflammation lesions. I was told PPMS 50% are clear. Anybody else experenced this.

@jolea , there's a booklet about PPMS here:- https://support.mstrust.org.uk/file/store-pdfs/Primary_Progressive_MS_2017.pdf Page 25 suggests a different percentage for Lumber Puncture results.......
