--in a long time, it might behoove you to get one with the increased symptoms. There's no rule that these conditions must remain static or progress only slowly. It's also possible that something new might have happened that is exacerbating the neuropathy.

Many of us use the Liz Jane spreadsheets as well as the Quest/Latov serological test article as starting points for our work-ups:

One thing I would suggest, if you've never had this done before, since you mentioned the protein in spinal fluid and the polycolonal increase in immunoglobulins from that serum protein electrophoresis: try to have the more specific and exacting immunofixation electrophoresis of serum and urine done (this is on the Latov/Quest list) to look for monoclonal antibodies (M-proteins) which are certainly associated with neuropathies. The serum protein electrophoresis is not specific enough as a small elevation in gamma globulins can be obscured in that test.
