What is Pinched Nerve?
The term pinched nerve describes one type of damage or injury to a nerve or set of nerves. The injury may result from compression, constriction, or stretching. Symptoms include numbness, "pins and needles" or burning sensations, and pain radiating outward from the injured area. One of the most common examples of a single compressed nerve is the feeling of having a foot or hand "fall asleep." Pinched nerves can sometimes lead to other conditions such as peripheral neuropathy, carpal tunnel syndrome, and tennis elbow. The extent of such injuries may vary from minor, temporary damage to a more permanent condition. Early diagnosis is important to prevent further damage or complications. Pinched nerve is a common cause of on-the-job injury.
Pinched nerve in the neck or lower back
A pinched nerve in the neck or lower back can be caused by a herniated disc, arthritis, bone spurs, or spinal stenosis.
Spinal stenosis is a narrowing of the spinal canal through which the nerves pass with the spine. A pinched nerve in the lower back or buttock can compress the sciatic nerve, which can cause sciatica.
