Walking is only easy if you are not in pain. I have diabetic neuropathy in my feet. This causes me extreme pain if I walk more than a certain distance, and that distance changes daily depending on how the neuropathy expresses itself on any given day. In addition to actual pain, neuropathy slowly causes my brain to lose communication with my feet, which means foot slapping, toe dragging, staggering, and sometimes tripping. I have trouble getting through my day in my large office building if I have to go to more than one meeting. There's no cure for it, nerve damage is permanent. Exercise doesn't fix it. Do you understand now, doctor?
