Ache and discomfort can possibly be felt more proximally in the forearm or even the upper arm. Numbness and paresthesias in the median nerve distribution are the hallmark neuropathic symptoms NS of carpal tunnel entrapment syndrome. Causes[ edit ] Anatomy of the carpal tunnel, showing the median nerve passing through the tight space it shares with the finger tendons Most cases of CTS are of unknown cause.
Symptoms Symptoms occur if the tissue in the carpal tunnel becomes swollen, putting pressure on the median nerve. Carpal tunnel syndrome is associated with the following symptoms: Parts of the hand feel numb or may tingle also called "pins and needles". Usually, the thumb and the middle three fingers are affected these appear red in the illustration.
Your hand falling asleep at night could be a typical early sign of carpal tunnel syndrome. Pain in your fingers: Sometimes the entire hand might also hurt, or the pain may radiate into your arm. These symptoms are most common at night and in the morning.
They usually affect both hands, but not necessarily at the same time. Shaking your hands often improves the symptoms. Return to top Causes It's often difficult to tell exactly what caused the tissue to swell.
Overextending or overusing the joint sometimes plays a role. This may happen if you, for instance, put too much pressure on your wrist, or overstretch or twist it. Repetitive activities like using a jackhammer, which makes the wrist vibrate a lot, can also cause the tissue to swell.
The symptoms of carpal tunnel syndrome often get worse when the wrist is exposed to this kind of physical strain. It's not clear whether they can also cause the condition, though. It's commonly believed that working at the computer can increase your risk of carpal tunnel syndrome, but research so far suggests that the effect is minor.
Some conditions can make you more likely to develop carpal tunnel syndrome. These include rheumatismdiabeteswrist injuries and repeated synovial inflammation. The symptoms may suddenly become very severe, but this only rarely happens.
Return to top Prevalence Carpal tunnel syndrome is most common between the ages of 40 and 70, and very rare in children. Women are more likely to be affected. People who do lots of physical labor are also more likely to have it.
It's estimated that about 3 out of 1, people develop carpal tunnel syndrome each year. Return to top Outlook Some people may have only mild symptoms which come and go over many years.
It's estimated that in about 1 out of 3 people the symptoms go away without treatment within six months. In others, the symptoms don't go away. If the condition worsens, the hand may feel numb all the time.
In later stages, carpal tunnel syndrome can cause the muscles on the ball of the thumb to waste away atrophy. If your hand becomes weaker and you can't feel it properly, it can be difficult to do everyday things like hold a teacup. Return to top Diagnosis Your doctor will first ask you about your symptoms and then examine your hand and wrist.
There are specific tests to see how well the hand and fingers can move and feel things. Electrophysiological tests like electroneurography ENG may also be needed to find out whether carpal tunnel syndrome is in fact causing the symptoms.
This test can measure how effectively the electrical signals are being carried by the nerves, and how well the nerves are working.
The results are considered together with the described symptoms, the physical exam, other life circumstances and your medical history. Ruling out other possible medical causes is also important.
For example, changes in the cervical spine the bones in your neck may irritate the nerve roots, causing similar symptoms. Other nervous system diseases such as polyneuropathy can also have this effect.Carpal Tunnel Syndrome Causes, symptoms & treatment information from our experienced Asheville hand surgeons Description.
Carpal tunnel syndrome is essentially a pinched nerve in the wrist.. There is a space in the wrist called the carpal tunnel where the median nerve and nine tendons pass from the forearm into the hand. Carpal tunnel syndrome is a common condition that causes pain, numbness, and tingling in the hand and arm.
The condition occurs when one of the major nerves to the hand — the median nerve — is squeezed or compressed as it travels through the wrist.

Many experts suggest that this increase is due to the additional amount of stress placed on our wrists and hands as a result of excessive smartphone and.
Carpal Tunnel Syndrome (CTS) is a type of repetitive strain illness that involves the swelling of tendons and compression of the median nerve which runs through the carpal tunnel in the wrist.
The median nerve controls both feeling and movement in the hand by sending messages from the brain to the hand. Carpal tunnel syndrome has similar symptoms – but they keep coming back again and are often painful.
The carpal tunnel is a passageway inside of the wrist that is surrounded by bones and connective tissue. Carpal Tunnel Syndrome can severely limit and restrict your lifestyle at home and work, as well as limit your leisure activities.
Diagnosis still proves to be a challenging task since it will still depend on a patient’s history, symptom description, pain severity, and a series of physical exams.
