Carpal tunnel syndrome features a compression of the median nerve inside the carpal tunnel. It is considered the most common nerve compression disease and affects 3% of the population worldwide. The carpal tunnel is a structure located in the wrist and includes the transverse carpal ligament and the carpal bones, which form the floor and the sides. The carpal tunnel contains 9 flexor tendons and the median nerve. The median nerve is the main nerve of the forearm that supplies the forearm frontal structure. Its wrist branches supply the skin and the muscles of the thumb, index, middle, half of the ring finger, and the outer 2/3 of the palm. When the space inside the carpal tunnel narrows, the compression on the nerve ensues. Median nerve compression causes tingling and numbness in the palm, thumb, index, and ring fingers. Carpal tunnel syndrome should be treated quickly to avoid serious complications arising from median nerve damage.
1What are the symptoms of carpal tunnel syndrome?
The following symptoms happen because of median nerve compression inside the carpal tunnel in the wrist. The compression usually occurs after inflammation and edema, which should be treated to reduce the pain and the symptoms of this disease.
Pain and numbness
Pain and paraesthesia, also known as numbness sensations, occur along with the distribution of the median nerve. They are the classic symptoms of carpal tunnel syndrome. Pain increases gradually in severity, intensity, and duration throughout the disease. The pain varies from aching pain or tingling to a stabbing, electric shock, burning or excruciating pain. Tinel’s sign is direct touching on the median nerve in the wrist areas will start the pain in the distribution of the median nerve. The pain usually increases at night because most people sleep with their hands bent. Patients with carpal tunnel syndrome experience numbness and tingling in the whole arm of the affected side and tend to shake their hands when they wake up because of nerve irritation and compression during the sleep. If the pain becomes severe, it may bebecause of nerve damage or separation of the median nerve in the carpal tunnel. Pain can also appear after holding items in hand for a prolonged period because it irritates the nerve especially after maintaining an abnormal wrist position.
