i have numb feet and lower legs and sometimes when you think you are putting your feet down correctly while walking you arent and you sprain your ankle and dont realize it pain wise because they are numb..which is what ive just done and now my ankle is badly swollen........ Ive fallen and broken my ankle before and sprained them many times. im afraid that long term my ankles will just break down and i wont be able to walk. i have peripheral neuropathy.
