--and has even been referred to with its own acronym--ASFAN--acute small fiber axonal neuropathy--in a few papers (some of which, if I recall, are linked to in the Useful Websites section of the board). My neuropathy, which occurred in hours/days, seems to fit into this category.

To clear up the "acute" vs. "sub acute" confusion--while there is some dispute about exactly what constitutes each, and there is some blurring at the borders, usually "acute refers to an onset time period of under two weeks, and "sub-acute usually refers to an onset time period of two to eight weeks. After that one usually gets into the realm of "chronic", in which changes in condition are not that noticeable on a day to day basis, but are only appreciated in longer term retrospect.
