What are the causes of pain after brachial plexus nerve injury?

Pain after brachial plexus nerve injury is a common neurosurgical condition, predominantly affecting infants, young children, and adult males. If not treated promptly, it can lead to severe complications such as muscle atrophy, joint stiffness, and permanent disability. When pain occurs after brachial plexus nerve injury, pharmacological treatment is usually required, with the most commonly used drugs being Vitamin B1, Vitamin B6, Vitamin B12, and diclofenac sodium.

1. Strain: Strain is the primary cause of pain after brachial plexus nerve injury. If a patient is caught in a machine conveyor belt or belt, it can lead to pain after brachial plexus nerve injury.

2. Collision injuries: Collision injuries are also a major cause of this condition. The most common collision injuries are those from traffic accidents, which can cause shoulder injuries, leading to pain after brachial plexus nerve injury.

3. Birth injuries: Birth injuries can also cause pain after brachial plexus nerve injury. If the baby is overly heavy, prenatal estimates are incorrect, or there are complications during delivery such as difficult labor, excessive pulling, and the use of forceps, these can all result in brachial plexus nerve injury.

4. Iatrogenic injuries: If an individual has a shoulder condition that requires surgery, improper handling during the surgical procedure can lead to pain after brachial plexus nerve injury. Brachial plexus nerve injuries are further classified into upper brachial plexus nerve injuries, middle brachial plexus nerve injuries, and lower brachial plexus nerve injuries. Symptoms vary depending on the location of the injury. Mild cases may present with temporary upper limb dysfunction and arm numbness, while severe cases may result in upper limb paralysis, muscle atrophy, and sensorimotor disturbances.
