No, None of my doctors over the years have felt that it would add value to my current diagnosis since they know I have axonal sensory PN. One said I couldn't also have SFN, but that has been disputed by people on here that know they have both. Regardless, the doctors have all said there is nothing they can do but help manage the symptoms, so I learn to live with it from the wealth of information and real life experience with PN on this forum!
