Anatomy
Carpal tunnel syndrome is a common source of hand numbness and pain caused by compression of the median nerve. The carpal tunnel is a narrow, tunnel-like structure in the wrist. The bottom and sides of this tunnel are formed by wrist (carpal) bones. The top of the tunnel is covered by a strong band of connective tissues called the transverse carpal ligament. The median nerve travels from the forearm into the hand through this tunnel in the wrist and can become irritated by the tendons that bend the fingers and thumb that also travel through the carpal tunnel.

The median nerve controls feeling in the palm side of the thumb, index finger, and long fingers. The nerve also controls the muscles around the base of the thumb. The tendons are called flexor tendons. The carpal tunnel protects the median nerve and flexor tendons that bend the fingers and thumb.
Common Symptoms
- Numbness or pain in your hand, sometimes worse at night
- Occasional hand tingling, numbness, pins-and-needles sensation
- Numbness or pain that worsens with use
- Hand or wrist pain with typing on computer
- Difficulty or pain with gripping, twisting, etc.
Cause
Carpal tunnel syndrome occurs when the tissues surrounding the flexor tendons in the wrist well and put pressure on the median nerve. These tissues are called synovium. The synovium lubricates the tendons and makes it easier to move the fingers. Swelling of the synovium narrows the confined space of the carpal tunnel and over time, crowds the nerve.
Carpal tunnel syndrome is caused by pressure on the median nerve traveling through the carpal tunnel. Many things contribute to the development of carpal tunnel syndrome. If any of these contributors of carpal tunnel pertains to you and you have pain in your wrists, contact us to schedule an appointment for the most innovative cryo treatments and active release techniques in your area.

- Heredity Factors Are Most Important Contributors– Carpal Tunnels Are Smaller In Some People And This Trait Can Run In Your Family
- Hand Use Over Time Can Play A Role
- Hormonal Changes Related To Pregnancy Can Play A Role
- Age – Carpal Tunnel Syndrome Occurs More Frequently In Older People
- Medical Conditions Like Diabetes, Rheumatoid Arthritis, And Thyroid Gland Imbalance Can Play A Role
