What causes numbness in both the left and right hands?

Numbness in both hands may be related to physiological factors, but it could also be caused by pathological conditions such as peripheral neuritis or cervical spondylosis. The specific analysis is as follows:

1. Physiological Factors

If a patient frequently lifts heavy objects over a prolonged period in daily life, excessive strain on the hands may compress local nerves, leading to hand numbness. In the absence of other discomfort symptoms, this is considered normal and does not require special treatment. The patient can gently massage both hands to promote blood circulation and alleviate the numbness.

2. Pathological Factors

1) Peripheral Neuritis

Peripheral neuritis usually results from damage to peripheral nerves due to various causes. Clinical manifestations include sensory abnormalities in the distal extremities, as well as motor and autonomic nerve dysfunction, such as limb numbness, tingling, burning sensations, etc. Patients may take medications under medical guidance, such as hydrocortisone acetate tablets or dexamethasone acetate tablets.

2) Cervical Spondylosis

Cervical spondylosis is typically a disease caused by degenerative changes in the cervical spine. When the cervical vertebrae compress surrounding nerves, it may lead to symptoms such as neck and back pain, stiffness, numbness and weakness in the limbs, movement difficulties, dizziness, and nausea. Patients may follow medical advice to take medications like celecoxib capsules or indomethacin capsules for symptom relief.

Besides the common causes mentioned above, bilateral hand numbness may also be associated with diseases such as diabetes, gout, or stroke. If symptoms persist without improvement, patients should seek timely medical evaluation and treatment at a hospital.
