Health Alert: Let’s talk “Pinch Nerves” with Dr. Duane Patten

Sometimes too much pressure is applied to our nerves causes us to have “pinch nerve” and to helping us to understand more about this ailment is Dr. Duane Patten, Neurosurgeon and Spine Surgeon.

What is a Pinched Nerve?

A pinched nerve occurs when too much pressure is applied to a nerve by surrounding tissues, such as bones, cartilage, muscles or tendons. This pressure can cause pain, tingling, numbness or weakness. A pinched nerve can occur in many areas throughout the body. For example, a herniated disk in the lower spine may put pressure on a nerve root. This may cause pain that radiates down the back of your leg. Likewise, a pinched nerve in your wrist can lead to pain and numbness in your hand and fingers (carpal tunnel syndrome). With rest and other conservative treatments, most people recover from a pinched nerve within a few days or weeks. Sometimes, surgery is needed to relieve pain from a pinched nerve.

Symptoms

Pinched nerve signs and symptoms include:

• Numbness or decreased sensation in the area supplied by the nerve
• Sharp, aching or burning pain, which may radiate outward
• Tingling, pins and needles sensations (paresthesia)
• Muscle weakness in the affected area
• Frequent feeling that a foot or hand has “fallen asleep”

The problems related to a pinched nerve may be worse when you’re sleeping.

When to see a doctor

See your healthcare provider if the signs and symptoms of a pinched nerve last for several days and don’t respond to self-care measures, such as rest and over-the-counter pain relievers.

Pinched median nerve

However, in some cases, this tissue might be bone or cartilage, such as in the case of a herniated spinal disk that compresses a nerve root. In other cases, muscle or tendons may cause the condition. In the case of carpal tunnel syndrome, a variety of tissues may be responsible for compression of the carpal tunnel’s median nerve, including swollen tendon sheaths within the tunnel, enlarged bone that narrows the tunnel, or a thickened and degenerated ligament.

A number of conditions may cause tissue to compress a nerve or nerves, including:

• Injury
• Rheumatoid or wrist arthritis
• Stress from repetitive work
• Hobbies or sports activities
• Obesity

If a nerve is pinched for only a short time, there’s usually no permanent damage. Once the pressure is relieved, nerve function returns to normal. However, if the pressure continues, chronic pain and permanent nerve damage can occur.

Risk factors

The following factors may increase your risk of experiencing a pinched nerve:

• Sex. Women are more likely to develop carpal tunnel syndrome, possibly due to having smaller carpal tunnels.
• Bone spurs. Trauma or a condition that causes bone thickening, such as osteoarthritis, can cause bone spurs. Bone spurs can stiffen the spine as well as narrow the space where your nerves travel, pinching nerves.
• Rheumatoid arthritis. Inflammation caused by rheumatoid arthritis can compress nerves, especially in your joints.
• Thyroid disease. People with thyroid disease are at higher risk of carpal tunnel syndrome.

Other risk factors include:

• Diabetes. People with diabetes are at higher risk of nerve compression.
• Overuse. Jobs or hobbies that require repetitive hand, wrist or shoulder movements, such as assembly line work, increase the likelihood of a pinched nerve.
• Obesity. Excess weight can add pressure to nerves.
• Pregnancy. Water and weight gain associated with pregnancy can swell nerve pathways, compressing your nerves.
• Prolonged bed rest. Long periods of lying down can increase the risk of nerve compression.

Prevention

The following measures may help you prevent a pinched nerve:

• Maintain good positioning — don’t cross your legs or lie in any one position for a long time.
• Incorporate strength and flexibility exercises into your regular exercise program.
• Limit repetitive activities and take frequent breaks when engaging in these activities.
• Maintain a healthy weight.
