The most common cause of foot lift is common peroneal nerve palsy. The common peroneal nerve is a branch of the sciatic nerve, which can cause common peroneal nerve palsy if it is squeezed and compressed in the small head area of the fibula. It can also occur in higher areas, such as when a lumbar disc herniation compresses a nerve in the lumbar region, such as the lumbar 5 nerve, and common peroneal nerve palsy can occur. The common peroneal nerve is innervated by the anterior tibial muscle, the small toe and other toe extensors and tendons, and the long and short peroneal muscles. Therefore, after the paralysis of the common peroneal nerve, the anterior tibial muscle is paralyzed, and the toes will droop and not be able to lift upward or turn outward as a result of nerve damage. At this time, you need to use nerve-nourishing drugs, such as internal methylcobalamin, vitamin B1, adenosine cobalamin, neurotoxicity, etc. Please use the drugs under the guidance of a doctor.
