Pain in the hand can be a warning sign of nerve damage.

Arm injuries are a common problem. Common arm injuries include muscle strains, fractures, dislocations, or soft tissue damage. However, one serious injury is nerve plexus damage.

The brachial plexus is a network of nerves originating from the spinal cord in the neck, which controls the shoulder, elbow, wrist, and hand. Brachial plexus injuries can range in severity from mild to severe, according to the UK health website Medical News Today .

Damage to the brachial plexus can cause pain, muscle weakness, and even loss of motor function in the arm.

People with brachial plexus damage may experience symptoms immediately afterward, or they may develop over time.

Warning signs of brachial plexus injury include:

Pain

People with brachial plexus injuries will experience a burning, aching sensation. The pain radiates from the neck to the shoulder and arm. The pain can come on suddenly and intensely, but it can also be a persistent discomfort.

Numbness and tingling

People with injuries may experience mild to severe numbness or tingling in the arm or hand. Numbness may affect the fingers or a specific area of ​​the arm, depending on the location of the damaged nerve.

Muscle weakness

An injured arm may experience muscle weakness, making it difficult to lift, especially when gripping objects or performing everyday activities. This weakness may be due to partial or complete paralysis, depending on the severity of the injury.

Loss of mobility

In severe cases, victims may experience paralysis of some or all of the arm muscles, or even complete loss of function in the injured arm.

Experts recommend that if someone with an injury experiences pain, numbness, and muscle weakness, they should see a doctor as soon as possible, especially if the symptoms worsen. Even if the symptoms aren't severe, if they affect daily activities like working, dressing, or personal hygiene, treatment is still necessary, according to Medical News Today .
