The median nerve is an important nerve that runs down your forearm, through tissue in your wrist called the carpal tunnel, and into your fingers. This is the nerve that allows you full use of your fingers and brings sensation to your fingers and fingertips, except for your little finger. The carpal tunnel that the median nerve passes through is very small and very sensitive. If it becomes swollen or blocked in any way, then you will get carpal tunnel syndrome.

There are many ways to get carpal tunnel syndrome. If you break bones in your wrist or you get calcium deposits associated with arthritis, then you could get carpal tunnel syndrome. Repetitive use of the wrist in uncomfortable positions is one of the most common causes of carpal tunnel syndrome that affects millions of people each year. Being obese or having your body unexpectedly retaining fluid can also cause swelling in the carpal tunnel.

Carpal tunnel syndrome does not have to happen, even in work conditions that require repetitive movements. This condition can be prevented by using proper ergonomic furniture and equipment, taking breaks from your work where you loosen up your wrists and forearms, and improving your posture as you sit or stand at your workstation.[symptom-checker]If left untreated, carpal tunnel syndrome could lead to loss of sensation in the wrists and hands. And it could make it difficult to hold items with your hands. If persistent symptoms continue to get worse, then you should seek out medical assistance immediately.
