Looking for some advice. Had emg and found severe sensory damage and some motor damage both feet and legs up to knees. My pain has bothered me for several years but got much worse about 6 weeks ago. Met with neuro after emg. His exam consisted of me attempting heel and toe walking and checking reflexes. No reflexes on feet and one reflex of knee. He mentioned cidp and that was it. I haven’t met with my Pcp for follow up. What should I be asking? What tests should be done? I got the impression that the neuro isn’t concerned about dx and just treating the damage that has been done. Any help appreciated!
