The peroneal nerve controls the muscles that lift your foot. This nerve runs near the surface of your skin on the side of your knee closest to your hand. Activities that compress this nerve can increase your risk of foot drop. Crossing your legs. People who habitually cross their legs can compress the peroneal nerve on their uppermost leg.
It's also sometimes called drop foot, and can cause you to drag your foot on the ground when you walk. Foot drop is a sign of an underlying problem rather than a condition itself. This could be muscular, caused by nerve damage in the leg, or the result of a brain or spinal injury. Foot drop usually only affects one foot, but both feet may be affected, depending on the cause. It can be temporary or permanent.
