Carpal tunnel syndrome (CTS) is a common condition that affects the median nerve in the wrist, causing symptoms such as tingling, burning, or itching, and numbness in the palm of the hand and the fingers, particularly the thumb and index finger [1][2]. This condition, also known as median nerve entrapment or median nerve compression, develops gradually over time due to pressure on the median nerve within the wrist's carpal tunnel.

### How CTS Develops and Progresses

The symptoms of CTS often start slowly, becoming more noticeable at night or during repetitive hand movements like typing or tool use [1]. As the condition progresses, nerve damage can occur, leading to persistent numbness and hand weakness. Early symptoms might be brief and occur mainly during sleep, but they tend to worsen if left untreated [2]. In advanced stages, muscle wasting at the base of the thumb and chronic pain can develop, necessitating interventions like surgery to halt nerve damage [4].

### Common Causes

Repetitive wrist use, such as frequent typing, using a mouse, or manual labor involving vibration (construction, woodworking, landscaping), is a major cause of CTS [1][2][3]. Wrist injuries, including fractures or sprains, can alter the carpal tunnel’s shape and increase nerve pressure, sometimes causing symptoms years after the injury [1][3]. Inflammatory conditions like rheumatoid arthritis can cause swelling that compresses the median nerve [1][2]. Fluid retention caused by hormonal changes during pregnancy or menopause contributes to increased pressure in the carpal tunnel [1][2][3]. Certain medical conditions like diabetes, hypothyroidism, gout, lupus, and kidney failure raise the risk by causing nerve damage or swelling [1][2][3]. Genetic predisposition, having a naturally smaller carpal tunnel or a family history of CTS, increases the risk [1][3]. Occupational and ergonomic factors, such as jobs requiring prolonged wrist bending or extension and activities with poor wrist posture, also increase susceptibility [1][2].

### Risk Factors

Age and sex are significant risk factors for CTS, with women and people over 40 years old being more likely to develop the condition, potentially due to hormonal changes and anatomical differences such as smaller wrist size [1][2][4]. Obesity increases internal wrist pressure, contributing to risk [1]. Chronic conditions like diabetes and thyroid disorders are associated with higher CTS incidence [1][2]. Posture, maintaining the wrist in a flexed or extended position for long periods, aggravates nerve compression [1][2].

### Treatment and Prevention

Early recognition and management are crucial since CTS is treatable and often reversible if caught before becoming severe. Treatment may include lifestyle changes, wrist splinting, activity modification, and in more advanced cases, surgery to relieve nerve compression [2][4]. Preventative measures to reduce the risk of developing CTS include not gripping too hard, avoiding overbending the wrist, maintaining correct posture, and taking frequent breaks. Working on a computer may have a slight effect on the development of CTS, but using a keyboard with an elevated and curved surface may help reduce strain.

In summary, CTS develops through a combination of repetitive mechanical stress, anatomical factors, medical conditions, and sometimes genetics, progressing from mild intermittent symptoms to more severe nerve damage if untreated [1][2][3][4]. CTS is the most common and widely known of the entrapment neuropathies. In the United States, CTS affects approximately 5 million people each year. If left untreated, CTS can lead to serious pain and numbness, but early diagnosis and proper treatment can help bring relief sooner and avoid complications. Wrist splints are available over the counter and can prevent the wrist from bending, while resting the hand and wrist can help relieve CTS symptoms. Applying cold compresses may help during a CTS flare-up, but not directly onto the skin. It is essential to remember that a person should not self-diagnose or try to treat CTS without seeking guidance from a healthcare professional.
