Tingling sensation in foot mostly caused by peripheral nerve damage. Your peripheral nerve might have been injured during operation or in accident. Nerve damage is almost always permanent as nerve tissue does not grow back easily. One can only prevent further damage by identifying its cause and taking treatment, but the damaged nerve cannot be repaired. There is a window period of a few days between getting tingling sesation and the nerve being permanently damaged. Thus, if tingling sensation in foot is treated during this period, the permanent damage to nerves can be avoided. Advice 1. Methylcobalamin 500 mcg once daily per oral for 3 months 2. Take proper rest Thanks
