###Human: I recovered from left side paralysis. Why do I face difficulty in left leg while walking? ###Assistant: Hi. I suggest you wear well-cushioned footwear made of MCR (microcellular rubber) material. It will help you to reduce the impact on the bone while walking and it reduces the pain. Keep yourself warm by wearing socks and avoid exposure to cold. Pain in cold temperature occurs due to decreased blood flow to the foot. Do continuous exercise to maintain function, and this will also help you to come out from your current issues. Keep walking regularly.
