Hello @bmars, I would like to add my welcome to Connect along with @j77, @ray666, @SusanEllen66 and others. I am sorry to hear that you are struggling with a diagnosis and being so young at 22 years old. It sounds like you have seen different neurologists with no diagnosis or cause for the sudden numbness that worked it's way from head to toe over a span of a few weeks. There can be many causes of numbness. Mayo Clinic has some information on the causes here - https://www.mayoclinic.org/symptoms/numbness/basics/causes/sym-20050938.

Have you thought about seeking help at a teaching hospital or major health facility that use a multidisciplinary teamwork approach to diagnose and treat patients?
