WHY DOES MY Neck causes pin and needles in left arm?

1. Cervical radiculopathy: This is the most common cause of neck pain causing pin and needles in the left arm. Radiculopathy occurs when one or more of the nerves that run from the spinal cord to the arm are compressed or irritated. This can happen as a result of a number of conditions, such as:

Herniated disk: A herniated disk occurs when the soft inner material of a spinal disk leaks out and puts pressure on a nerve.

Bone spurs: Bone spurs are bony growths that can develop on the vertebrae and narrow the spinal canal, putting pressure on the nerves.

Degenerative spinal conditions: Degenerative conditions of the spine, such as osteoarthritis and spinal stenosis, can cause narrowing of the spinal canal and compression of the nerves.

2. Thoracic outlet syndrome (TOS): TOS is a condition that occurs when the nerves and blood vessels that run from the neck to the arm are compressed. This can happen as a result of a variety of factors, such as:

An abnormal bone structure of the ribs or collarbone

. a muscle spasm in the shoulder or neck

. a blood clot or tumor

3. Brachial plexopathy: Brachial plexopathy is a condition that affects the brachial plexus, a network of nerves that runs from the spinal cord to the arm. This can happen as a result of a variety of factors, such as:

.Trauma

.a stroke

.a tumor

If you are experiencing neck pain accompanied by pin and needles in your left arm, it is important to see your doctor to determine the cause and receive appropriate treatment.
