What causes numbness and weakness in a woman's right hand?

Generally, right hand numbness and weakness in women may be caused by improper sleeping posture, overexertion, multiple sclerosis, carpal tunnel syndrome, cervical spondylosis, and other factors. Symptomatic management through general treatment and medication may be necessary. If discomfort persists, it is recommended to seek timely medical attention and undergo appropriate treatment under a doctor's guidance. Detailed analysis is as follows:

1. Improper Sleeping Posture

Excessive pressure on the right hand during sleep can lead to poor blood circulation and nerve compression, resulting in numbness and weakness. Symptoms typically occur after sleeping and gradually subside after waking. It is recommended to improve sleeping posture and avoid pressure on the right hand.

2. Overexertion

Long-term heavy physical labor, desk work, typing, and similar activities may cause nerve damage or compression in the arm or wrist, leading to hand numbness and weakness. Symptoms may be accompanied by soreness or pain in the arm or wrist. It is recommended to rest adequately, avoid excessive exertion, and engage in appropriate wrist-relaxation exercises.

3. Multiple Sclerosis

Multiple sclerosis is primarily caused by a combination of autoimmune responses, viral infections, genetic factors, and others. The immune system mistakenly attacks the myelin sheath of the central nervous system, impairing nerve signal transmission and causing symptoms such as limb weakness and sensory abnormalities. Additional symptoms may include blurred vision, balance disorders, and fatigue. It is recommended to follow medical advice and use medications such as glatiramer acetate injection, dimethyl fumarate enteric-coated capsules, and teriflunomide tablets for treatment.

4. Carpal Tunnel Syndrome

Carpal tunnel syndrome is mainly caused by long-term overuse of the wrist, wrist injuries, or chronic fatigue. The median nerve within the carpal tunnel becomes compressed due to anatomical narrowing or surrounding tissue proliferation, leading to nerve conduction disturbances. This results in finger numbness, tingling, and hand weakness. It is recommended to follow medical instructions and use medications such as ibuprofen tablets, mecobalamin tablets, and adenosylcobalamin tablets to alleviate symptoms.

5. Cervical Spondylosis

Chronic strain and degeneration of the cervical spine may lead to cervical spondylosis. Abnormal changes in the cervical spine can compress nerve roots, impairing their conduction function and causing sensory and motor dysfunction in the corresponding areas, resulting in hand numbness and weakness. Symptoms may be accompanied by neck pain, shoulder discomfort, and radiating arm pain. It is recommended to follow medical advice and use medications such as aceclofenac tablets, Jingfukang granules, and mecobalamin tablets for treatment.

It is recommended to appropriately strengthen arm exercises in daily life—for example, performing simple arm-strengthening exercises with light dumbbells—which may help reduce the occurrence of hand numbness and weakness.
