Symptoms and diagnosis for Carpal Tunnel Syndrome
Carpal Tunnel Syndrome is a painful, progressive condition caused by compression of the median nerve at the carpal tunnel. The carpal tunnel is a narrow space bound by carpal or wrist bones and ligaments. The median nerve and the flexor tendons pass through this tunnel from the forearm to the hand. When the nerve is squeezed it can cause tingling, numbness, pain or aching in the affected hand.
One may feel a burning, tingling, or itching numbness in the palm of the hand and thumb, or index and middle fingers.
We might first notice that our fingers “fall asleep” and become numb at night. That usually happens in the evening because of the relaxed position of our hand and while sleeping.
In the morning, we may wake up with numbness and tingling in our hands that may run all the way to our shoulder.
As carpal tunnel syndrome becomes more severe, we may have less grip strength because the muscles in our hand shrink. Pain and muscle cramping will also become worse.
The median nerve begins to lose function because of the irritation or pressure around it. This leads to:
We could end up with permanent muscle damage and lose function in our hand.
“The risk of developing carpal tunnel syndrome is not confined to people in a single industry or job, but is especially common in those performing assembly line work – manufacturing, sewing, finishing, cleaning, and meat, poultry, or fish packing. In fact, carpal tunnel syndrome is three times more common among assemblers than among data-entry personnel. “
Our doctor may ask and conduct one or more of the following tests to determine whether you have carpal tunnel syndrome:
History of symptoms. Our doctor will review the pattern of your symptoms. Carpal tunnel syndrome symptoms usually occur include while holding a phone or a newspaper, gripping a steering wheel, or waking up during the night.
Physical examination. Our doctor will conduct a physical examination. He will test the feeling in your fingers and the strength of the muscles in your hand.
Bending the wrist, tapping on the nerve or simply pressing on the nerve can trigger symptoms in many people.
Symptoms may often be relieved without surgery. Some treatment options are:
When symptoms are severe or do not improve, surgery may be needed to make more room for the nerve. Pressure on the nerve is decreased by cutting the ligament that forms the top of the tunnel on the palm side of the hand. Following surgery, soreness around the cut area may last for several weeks or months. The numbness and tingling may disappear quickly or slowly. Recovery may take several months. Carpal tunnel symptoms may not completely go away after surgery, especially in severe cases.
