Why do my feet go numb after sitting for a long time?

Generally, numbness in the feet after prolonged sitting may be a normal physiological phenomenon, or it could be caused by medical conditions such as cervical spondylosis or lumbar disc herniation. Symptoms can be relieved through medication or traditional Chinese medicine therapies.

1. Normal physiological phenomenon: Prolonged sitting can compress the muscles and nerves in the legs, affecting blood circulation and leading to leg numbness. This is considered a normal physiological response that does not require special treatment. Usually, symptoms resolve after a few minutes of movement.

2. Cervical spondylosis: This condition may result from excessive physical activity or sleeping with a pillow that is too high. It can cause symptoms such as foot numbness after prolonged sitting and reduced limb mobility. Symptoms can be alleviated through treatments like traction therapy or acupuncture.

3. Lumbar disc herniation: This condition is often caused by repeated bending or long-term heavy physical labor. Common symptoms include foot numbness after sitting for extended periods and lower back pain. Treatment may involve medications such as compound chlorzoxazone tablets or tizanidine hydrochloride tablets, used according to medical advice.
