Pinched Nerve – Symptoms and Causes
A pinched nerve happens when surrounding tissues press too hard on a nerve. These tissues can include bones, cartilage, muscles, or tendons.
This pressure often causes uncomfortable symptoms like pain, tingling, numbness, or weakness in the affected area.
Pinched nerves can occur throughout the body. In the lower spine, a herniated disk might compress a nerve root, causing pain that travels down the leg.
In the wrist, nerve compression can lead to carpal tunnel syndrome, with symptoms affecting the hand and fingers.
Most people get better from pinched nerves within days or weeks. They do this by resting the affected area, taking anti-inflammatory medications, applying ice or heat, and doing gentle stretches.
Surgery may be needed to relieve nerve pressure if symptoms are severe or do not improve with conservative treatment.
Signs and Discomfort
A compressed nerve can lead to a variety of symptoms. You might feel numbness in the area where the nerve runs.
Pain that is sharp, aching, or burning may spread outward from this spot. Many people also notice tingling or pins-and-needles feelings.
Muscle weakness may develop in affected areas. The sensation resembles a hand or foot that has “fallen asleep.” These symptoms can worsen when you are trying to sleep.
When Medical Help Is Needed
Rest and over-the-counter pain medications often help relieve compressed nerve symptoms. However, you should contact your healthcare provider if your symptoms:
- Continue for several days
- Don’t improve with self-care measures
- Interfere with daily activities
- Get worse over time
Seeking timely medical attention can help prevent long-term nerve damage.
Causes
A pinched nerve happens when surrounding tissues put too much pressure on a nerve. Different types of tissue can cause this compression:
- Bones and cartilage (like a herniated disk pressing on a nerve root)
- Muscles and tendons
- Swollen tendon sheaths
- Enlarged bones
- Thickened or degenerated ligaments
Several conditions may lead to this nerve compression:
- Physical injury to the affected area
- Inflammatory conditions such as rheumatoid arthritis or wrist arthritis
- Repetitive stress from work activities
- Recreational activities, including certain hobbies and sports
- Excess body weight puts pressure on nerves
When a nerve experiences compression for only a brief period, the damage is usually temporary. Normal nerve function typically returns once the pressure is relieved. However, long-term compression can result in chronic pain and permanent nerve damage.
Carpal tunnel syndrome occurs when tissues in the wrist compress the median nerve in the carpal tunnel.
Risk Factors
Several factors can increase your chance of developing a pinched nerve:
- Gender Differences: Women face a higher risk for carpal tunnel syndrome because they typically have smaller carpal tunnels.
- Bone Issues: Bone spurs from injuries or conditions like osteoarthritis can narrow nerve pathways and cause pinching.
-
Health Conditions:
- Rheumatoid arthritis inflammation can press on nerves, especially in joints
- Thyroid disorders increase carpal tunnel syndrome risk
- Diabetes makes nerve compression more likely
-
Lifestyle Factors:
- Repetitive movements from work or hobbies (assembly line jobs, etc.)
- Extra body weight puts additional pressure on nerves
- Pregnancy causes fluid retention and weight gain, which may compress nerves
- Extended bed rest increases compression risk
Prevention
Protecting yourself from nerve compression requires several simple steps.
- Maintain proper posture throughout the day. Avoid crossing your legs for extended periods. Change positions regularly when sitting or lying down.
- Exercise regularly, with a focus on building strength and improving flexibility. These activities help keep muscles strong and joints mobile.
- Take breaks during repetitive tasks to give your body time to recover. This reduces strain on nerves and surrounding tissues.
- Keep a healthy weight to minimize pressure on your nerves, especially those in your spine and limbs.
