T14.4: Injury of nerve(s) of unspecified body region

Most nerves have various functions at the same time. 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. The other part is vital for sensing touch or warmth on the skin. If this part is damaged, then the skin may be numb or tingle. Where exactly the symptoms appear depends on where the nerve was damaged.
