There may be several causes for numbness in the right hand and right leg. The following are some common causes:
1. Sequelae of trauma: Soft tissue or nerve damage caused by external forces may lead to local circulatory disturbances and nerve dysfunction, resulting in limb numbness.
2. Cervical spondylosis: Long-term improper posture or other factors may cause degenerative changes in the cervical intervertebral discs. When adjacent cervical spinal cord is compressed, it can cause sensory loss in the extremities, leading to numbness.
3. Lumbar disc herniation: Degeneration of intervertebral discs, rupture of the annulus fibrosus, and other factors may cause the nucleus pulposus to protrude backward, compressing the dural sac and nerve roots, causing numbness, weakness, and other symptoms in the lower limbs.
4. Circulatory problems: Maintaining the same posture for a long time, such as sitting or standing for prolonged periods, may lead to poor local blood circulation, which can cause numbness. Symptoms usually improve after changing posture.
5. Diabetic neuropathy: Poor long-term control of blood glucose levels can damage nerves throughout the body, especially those in the extremities, causing numbness, pain, or tingling in the hands and feet.
If symptoms persist or are accompanied by other severe symptoms, it is recommended to seek timely medical attention for early diagnosis and treatment.
