Every morning when you wake up with numbness in your arms, the first thing to consider is that it is caused by cervical spondylosis. Generally, cervical spondylosis is caused by the protrusion or acromegaly of the cervical disc, resulting in compression of the dural sac or nerve roots, and the patient may experience numbness in the arms, and in severe cases, weakness in the arms. If necessary, CT or MRI of the cervical disc can be used to confirm the diagnosis. The main treatment is to give traction, acupuncture, massage and other symptomatic treatment. Secondly, arm numbness in the morning can also be seen in transient ischemic attacks, which are generally common in the elderly. Due to the slowing down of blood flow after a long period of sleep at night, the blood is in a high-fat and high-viscosity state, and the patient can experience transient cerebral ischemic attack and neurological deficits. It is usually accompanied by dizziness, headache, numbness and weakness of the limbs. If necessary, CT or MRI of the head can be performed. Treatment is mainly given to antiplatelet aggregation, blood circulation and improvement of circulation and other symptomatic treatment.
