Why would my arms and hands become totally numb within 2 hours of going to sleep?

Possible causes of arms and hands becoming totally numb within 2 hours of going to sleep include:

- Peripheral neuropathy: This is a condition that affects the nerves in the arms and hands. It can be caused by a variety of factors including diabetes, alcoholism, chemotherapy, and vitamin B12 deficiency.

- Carpal tunnel syndrome: This is a condition that occurs when the median nerve, which runs from the forearm to the palm of the hand, becomes compressed. It can be caused by repetitive hand motions, such as typing or working with tools.

- Thoracic outlet syndrome: This is a condition that occurs when the nerves and blood vessels in the thoracic outlet, which is the space between the collarbone and the first rib, become compressed. It can be caused by a variety of factors, such as poor posture, obesity, and trauma.

- A pinched nerve: This can occur when a nerve is compressed by nearby tissues, such as bones, muscles, or tendons. It can be caused by a variety of factors, such as trauma, inflammation, and tumors.

- A stroke: This occurs when the blood supply to the brain is interrupted, which can damage the areas of the brain that control movement and sensation.
