The dangers of leg numbness

Numbness in the legs and feet is mostly caused by sitting, standing or squatting for a long time due to poor posture. The blood circulation in the legs is poor, and the peripheral nerves are compressed, which affects the normal conduction of the nerves. The stimulation received cannot be accurately and timely transmitted to the brain to remind us to change posture, so the legs and feet will become numb after circumcision. In addition, maintaining the same posture for a long time can also compress the tibial nerve or peroneal nerve, causing nerve paralysis symptoms and numbness in the legs and feet.
