The herniated disc as the cause

In the event of a herniated disc of segment L5, the core of the disc slips from its original position and presses on the nerve roots or nerve fibers in the area of the spinal canal. If the nerves of segment L5 are damaged, various symptoms occur. On the one hand, sensitivity disorders occur in the area of the inner thigh and foot.

The patient expresses this as an unpleasant tingling sensation or numbness. On the other hand, it is also possible that the motor nerve fibers that supply the foot muscles are damaged by the herniated disc in the area of the spine. This can then result in foot lifter paresis.

Other accompanying symptoms

Foot lifter paresis often has dramatic consequences for the person affected. An intact function is of great importance for walking and climbing stairs. In the event of a loss of function, the patient is therefore extremely restricted.

Depending on the cause of the foot lifter paresis, other accompanying symptoms may also occur. In the case of a slipped disc, for example, these include back pain, which can often radiate into the foot. Feelings of numbness in the area of the leg or the back of the foot can also be accompanying symptoms of foot lifter paresis.

Sometimes an accompanying sensory disturbance also only manifests itself as an unpleasant tingling sensation. A serious herniated disc in the area of L5 can also cause a disturbance of the nervous system of organs. This leads to bladder and rectal voiding disorders.

The affected patients are incontinent and can no longer control the outflow of urine and stool willingly. Whether one has pain with foot lifter paresis depends on the underlying disease. A herniated disc in the L5 region usually causes severe pain.

Emotional disorders are also corresponding accompanying symptoms. If the peroneal nerve in the area of the head of the fibula is damaged by pressure, for example if you kneel too long or cross your legs, pain is usually not an accompanying symptom. Even slowly growing tumors that damage the nerve often cause no pain.
