BLOG 569 CARPAL TUNNEL
Chronic, lingering wrist pain that causes discomfort for
daily living activities may be attributed to carpal tunnel syndrome (CTS). When
pain, tingling, and/or numbness is felt in some of the fingers, there can be
nerve compression. This uncomfortable feeling can be attributed to the median
nerve. This nerve runs down the arm, through the wrist, and then to the
fingers. The route the nerve takes is through the carpal “tunnel”. Movement of
all fingers (except the pinky) are controlled by this very nerve. When swelling
occurs, the “tunnel” becomes narrowed. There are about 200,000 cases of CTS per
year in the U.S. which correlates with our excessive nature.
Repetition
We live in a world of repetition. Our hands are a vital part
of many actions that we take. Most tasks require our hands, fingers, and
wrists. We write, type, put our shoes on, open doors, eat, and this list of
hand work could go on and on. These are the very repetitive movements that can
lead to CTS but other culprits include pregnancy (but it can go away), obesity,
diabetes, arthritis, and hypothyroidism. Due to these conditions, the wrists
are being asked to work under excess weight conditions or through hormonal
imbalances that affect joint motion. It is more commonly found among women,
possibly because the “tunnel” is naturally smaller. Certain jobs that have
repetitive functions also increase the likelihood of CTS. These might include
jobs such as a hairdresser, cashier, musician, baker, or someone in an assembly
line who does the same movement over and over.
Symptoms
When early detection is possible, a person might feel
burning, itching, or numbness in their palm or fingers. Your fingers might even
fall asleep. This pain can travel up to the shoulder. If the symptoms increase,
you might lose your grip. Eventually strength in the wrist decreases.
Diagnosis/Treatment
There are a couple tests for CTS. Besides a doctor’s general
inspection of your wrist mobility, you can have a test called EMG-NCV done. This
measures the degree of the median nerve function. Upon diagnosis a doctor might
tell you to keep the wrist immobile. Using a splint can help lessen the
pressure on the median nerve. This is basically helping that nerve rest. Medications
are available to help with the inflammation. Steroid shots can be done. Worst case
scenario is surgery, but this can be done to correct the problem.
Even a teacher who grades paper after paper can experience
carpal tunnel syndrome. We don’t realize how much we do and how many times we
do these tasks, until suddenly they are painful. CTS doesn’t happen overnight;
it is over and overuse. Years later we might feel the side. Like most other
elements of life, moderation is key. Take breaks and watch your form. Moderate
your repeat functions. Keep the tunnel open…. not backed up with traffic that
leads to frustration and lack of movement.
