Numbness in the feet is most commonly caused by local nerve compression or abnormal local nerve function, and requires further examination at the hospital. In general, this symptom is often associated with the following diseases.
1. Diabetes: Long-term diabetes can cause peripheral neuropathy, which can lead to numbness in the feet. In this case, it is necessary to actively control blood sugar and take oral nerve-nourishing drugs for treatment.
2. Diseases such as lumbar disc herniation and lumbar strain: Once the herniated disc compresses the nerve, the patient will experience numbness in the foot. If the symptoms are mild, they can be treated conservatively; once the symptoms are severe, timely surgery is recommended.
3. Lower extremity venous thrombosis: When compression of the patient’s nerve causes numbness in the foot, the patient needs to be treated promptly at a hospital internal medicine department.
4. Cerebral infarction: When cerebral infarction occurs, the patient may also experience numbness in the hands and feet, or even hemiparesis.
