What are Pinched Nerves?
Definition: The term pinched nerve describes one type of damage or injury to a nerve or set of nerves.The term “pinched nerve” is often used as a catch-all phrase for injuries resulting 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.” According to A.D.A.M., at some time, up to 40% of people experience pain, known as sciatica, which occurs when the sciatic nerve is trapped or inflamed. The sciatic nerve is the one most likely to be affected in low back pain. Aside from sciatica, pinched nerves can sometimes lead to other conditions such as • peripheral neuropathy • carpal tunnel syndrome • tennis elbow (compression of the ulnar nerve at the elbow) The extent of pinched nerve injuries may vary from minor, temporary damage to a more permanent condition.

Pinched nerve is a general term for pain in a nerve or impaired function of a nerve that is under pressure. This happens to nerves that control muscle movements and to nerves that relay sensations to the brain. Common causes of pinched nerves include: • Bulging discs in the spine, causing back, leg or shoulder pain. • Compression of a nerve at the elbow or wrist. • A prolonged cramped posture. • Arthritis. • An abnormal bone growth, such as a bone spur in the foot. • Use of a cast or crutches. • Repetitive motion on the job. or • A tumor. The initial symptoms of a pinched nerve may be tingling, numbness, a burning sensation, or shooting pains. Sometimes the pains and sensations are somewhat distant from the point of pressure. If there is nerve damage from constant pressure, pain and weakness may increase. There may be a loss of reflexes or movement skills. Finally, there may be a loss of sensation in the affected area. The following steps may relieve discomfort from a pinched nerve: •
