S64: Injury of nerves at wrist and hand level
S64.1: Injury of median nerve at wrist and hand level
Many nerves run from the spinal cord and brain to the organs, skin and muscles in the body. Most nerves have various functions at the same time. For example, part of the nerve controls specific muscles. If this part is damaged, you may no longer be able to use that muscle strongly or at all. Another part of the nerve can be vital for sensing touch or heat on the skin.
Where exactly the symptoms appear depends on where the nerve was damaged. You have damaged your median nerve. The median nerve is important in flexing your hand. The nerve is also important for sensation on the inside surface of the hand. The nerve begins at the top, at the shoulder, and runs down to the hand. In your case, the nerve has been damaged in your hand.
