Two very small patches of numbness in both feet which remained the same for about 2 years before starting on a course of slow progression. The outer sides of my feet, then my big toe. Nothing is completely numb, but I fear will be someday. I have had two EMG/NCS. The first concluded minor idiopathic neuropathy, the second revealed Radiculopathy coming from the L5 area in my back. I have back pain only occasionally, and very mild pins and needles radiating down my leg. I’m thinking it may be a combination of something systemic and my back. My symptoms initially began after knee surgery but who knows if that is related. I’ve also had all the usual blood tests.
