Carpal Tunnel (Repetitive Stress Injury)
WebMD explains that Carpal tunnel syndrome is pain, tingling, and other problems in your hand because of pressure on the median nerve in your wrist. The median nerve and several tendons run from your forearm to your hand through a small space in your wrist called the carpal tunnel. Pressure on the median nerve causes carpal tunnel syndrome. This pressure can come from swelling or anything that makes the carpal tunnel smaller, including: Illnesses such as hypothyroidism, rheumatoid arthritis, and diabetes.
- Pregnancy.
- Obesity.
- Wrist injuries and bone spurs.
- Smoking, because it can reduce blood flow to the median nerve.
