Your peripheral nerves link your brain and spinal cord to the other parts of your body, such as your muscles and skin. Peripheral nerves are fragile and easily damaged. A nerve injury can interfere with your brain's ability to communicate with your muscles and organs.
If you feel tingling or numbness in your leg, arm or hand, you may have injured one or more nerves when you had an accident or broke a bone. Weakness in one of those places can also mean that you've injured your sciatic or radial nerve. It's important to get medical care for such an injury as soon as possible because nerve injuries can be repaired. Evidence suggests that you can heal better when you have a severe nerve injury repaired soon after your injury.
