The median nerve runs along the carpal tunnel, or on the palm side of your hand. This nerve is the reason you feel sensations in your thumb, index finger, middle finger, and ring finger. It also innervates movements of the thumb.
Individuals experiencing carpal tunnel syndrome often feel pain, tingling, and numbness in their wrist, hands, and fingers. These symptoms frequently gradually arise. Sometimes, they get worse at night. Further, some may find their grip strength significantly decreases. They may feel weak, especially in the thumb muscles.
What causes carpal tunnel syndrome? The most common causes include repetitive movements with the wrist, rheumatoid arthritis, pregnancy, and obesity. Hypothyroidism is also thought to increase one’s risk of experiencing carpal tunnel syndrome. Other conditions that are closely associated with this condition include diabetes, high blood pressure, and injuries occurring at the wrist.
A common problem in today’s society involves the long hours sitting at a computer and typing on a keyboard. Consequently, this is one of the main reasons many individuals develop this uncomfortable and painful condition.
Treatment often entails resting the wrist affected. Wrist splints may also be recommended to promote healing and limit anymore repetitive movements. Pain medication may also help while the wrist heals and while inflammation subsides. Surgery is only recommended in very severe cases, such as those where the median nerve has been damaged.
