The causes of tingling of the little toe include physiological factors and disease factors. Physiological factors are mostly seen in shoes that do not fit; disease factors are mostly seen in lumbar disc herniation, pear-shaped muscle syndrome, peroneal nerve palsy and so on.
1. Physiological factors: most often seen in the shoes do not fit the feet lead to small toes long-term compression, resulting in poor local blood circulation, easy to lead to numbness. After removing the causative factors, the activity of little toes can be restored to normal.
2. Disease factors
(1) Lumbar intervertebral disc herniation: mainly the protruding nucleus pulposus compresses the nerves innervating the lower limbs, causing radiating pain in the lower limbs, usually accompanied by lumbar pain, numbness of the lower limbs and other symptoms.
(2) Piriformis syndrome: Piriformis syndrome can stimulate the sciatic nerve, resulting in the clinical manifestation of numbness of the little toes, which requires electromyography to determine the stimulation of the nerve by the piriformis muscle.
(3) Common peroneal nerve palsy: It may present as numbness of the little toe and the outer edge of the foot, in addition to which the patient may have a cross-threshold gait.
The etiology of numbness of the little toe is very complex, and it is necessary to consult a doctor in time, and under the guidance of the doctor to improve the relevant examinations to clarify the cause of the disease and then systematic treatment.
