Hand swelling and numbness may be related to overwork of the hands, or it may be caused by cervical spondylosis, diabetic peripheral neuropathy and other reasons.
1. Excessive hand fatigue: If you are engaged in heavy physical labor for a long time or carry out manual work for a long time, resulting in maintaining a fixed posture for a long time, which causes excessive fatigue of the hands, it may cause hand swelling and numbness.
2. Cervical spondylosis: especially in patients with cervical spondylotic hyperplasia or cervical disc herniation, it is easy to lead to local nerve root compression, resulting in dysfunction of the innervated parts of the nerves, which may cause hand swelling and numbness, and may be accompanied by upper limb weakness, numbness, neck and shoulder pain and other symptoms.
3. Diabetic peripheral neuropathy: this disease is usually caused by diabetic patients with poor long-term blood sugar control, which can lead to damage to the peripheral nerves, resulting in impeded blood circulation in the nerve endings, which may cause hand swelling, numbness, and may be accompanied by weakness, pain and other symptoms.
Hand swelling and numbness may also be caused by other reasons, if the symptoms continue to be unable to relieve, you should seek medical advice as soon as possible to confirm the diagnosis of the cause, and then give targeted treatment.
