What is the first line treatment for Peripheral Neuropathy? My dx was never specific. One neurologist indicated the following: Monoclonal Gammopathy or CIDP. I saw two others, one who felt their was evidence for Moderate Generalized Sensorimotor Polyneuropathy and then added that their was evidence for Neuromuscular Junctional impairment as seen in MG. The last one agreed with those findings and given the Meds I could take, IVIg was what they all offered and one also added Imuran. I realize the latter would not really make a difference until a year of use.
