Why Do My Hands Go Numb When I Sleep On My Back
Camila Farah
Extended pressure on the ulnar nerve in your arm interferes with the function of the nerve and makes the hand numb.
One of the most common causes of numbness in the hands at night is how you lay down. You will wake up with tingling arms or hands. The symptoms are worse if you suffer from an ulnar nerve entrapment. Lateral epicondylitis is called tennis elbow because it s caused by a repetitive motion like swinging a tennis racket.
These nerves are responsible for muscles in your hands and fingers. Sleeping with a bent elbow compresses the ulnar nerve. The repeated motion damages muscles and tendons in the forearm causing. Instead of laying down with your hands under you try sleeping with them free so that blood can flow and no nerves are pinched.
