Carpal Tunnel Syndrome

Introduction

The median nerve, radial nerve, and ulnar nerve are the three main nerves that supply the hand and upper extremity. It is common for these nerves to become compressed in the extremity causing symptoms such as numbness, tingling, weakness and pain.

The wrist is one of the most common joints where nerve compression occurs. When the wrist flexes or extends for a long period of time it can cause compression in an area of the wrist known as the carpal tunnel. As pressure increases, symptoms can worsen leading to nerve damage.

Most cases of carpal tunnel syndrome are caused by a variety of causes or etiologies. It can be hereditary, present as a symptom of pregnancy or develop as the result of the position of the hand and wrist as well as repetitive use of the hand. Other health conditions such as rheumatoid arthritis and thyroid gland imbalance can also affect the development of carpal tunnel syndrome.
