There are many potential causes of weakness and numbness in the hands. Some common causes include:
Carpal tunnel syndrome: As mentioned earlier, carpal tunnel syndrome occurs when the median nerve becomes compressed as it passes through the carpal tunnel in the wrist. This can cause weakness and numbness in the hand and fingers.
Peripheral neuropathy: Peripheral neuropathy is a condition that occurs when the peripheral nerves, which carry signals to and from the brain and spinal cord, are damaged. This can cause weakness, numbness, and tingling in the hands and feet.
Cervical radiculopathy: Cervical radiculopathy is a condition that occurs when a nerve in the neck becomes compressed or pinched. This can cause weakness and numbness in the hand and fingers.
Multiple sclerosis: Multiple sclerosis is a chronic autoimmune disease that affects the central nervous system. It can cause weakness and numbness in the hands and fingers, as well as other parts of the body.
Pinched nerve: A pinched nerve can occur anywhere in the body and can cause weakness and numbness in the affected area.
Diabetes: Diabetes can cause nerve damage, known as diabetic neuropathy, which can lead to weakness and numbness in the hands and feet.
It is important to see a healthcare provider for an evaluation if you are experiencing weakness and numbness in the hands, as it can be a sign of an underlying medical condition that requires treatment.
