Peripheral nerve injury occurs when nerves outside the brain and spinal cord are damaged. This can result from trauma, compression, or diseases like diabetes. Symptoms may include pain, numbness, tingling, or weakness in the affected area, depending on which nerve is injured. Treatment for peripheral nerve injury often involves physical therapy, medications, or surgery to repair the damaged nerve. Recovery can vary, with some individuals regaining full function while others may experience long-term effects. Early diagnosis and intervention are crucial for improving outcomes and minimizing complications related to peripheral nerve injuries.
