This is a numbing disorder
of the hand that rarely affects men but is fairly common in women.
The carpal tunnel is a passageway that leads through your wrist.
The area is called a tunnel because it has bones on three sides
and a ligament on the palm side. Feel your wrist. Can you feel that
it has three bony sides and soft tendons on the underside? The carpal
tunnel protects the median nerve that runs inside and provides sensation
to your fingers. Normally you aren't conscious of that nerve, but
when tissues in the tunnel swell, there's less room in the area
and the median nerve becomes irritated. People with carpal tunnel
syndrome (CTS) experience numbness, tingling and pain in the fingers,
wrist and even the arm. It is commonly described as pins-and-needles
tingling or fingers going to sleep, such as when you've rested on
a part of your body for a long time. The pain is worse at night
when your body is warm and blood vessels expand taking up more space
in the carpal tunnel. CTS may be brought about by activities that
involve repeated or strenuous use of the wrists. Repetitive motions
may range from typing all day at a computer to biking or playing
tennis on a regular basis. Staying in one position for so long that
it causes compression on the nerve such as during a long bike ride
may also cause CTS. Swelling and pressure - and carpal tunnel syndrome
- may also be caused by conditions such as arthritis, diabetes,
low levels of thyroid hormones, pregnancy, hormonal changes associated
with menopause and broken or dislocated bones in the wrist.
When sitting at a keyboard,
make sure your hands are at elbow level or slightly below elbow
level to prevent excess bending or stretching in the wrist. You
may also use a wrist rest that is a foam pad placed at the end of
the keyboard for extra support. Take a break every hour or two or
whenever you feel tired, to change your posture. Lean back and take
your hands off the keys. Take a second to bend your wrists the opposite
way from the position they normally maintain. Stretch your fingers
and shoulders, moving them around naturally to get them out of the
fixed position. Take a thick rubber band and place it around the
tips of your fingers including your thumb. Now open and close your
fingers. For more wrist exercises, you may squeeze a tennis ball
several times a day or try sports dough called "Power Putty" If
you ride bikes; you should wear properly padded biking gloves and
change positions during a long ride. If you play tennis or handball,
take lessons to learn the proper grip. If you are pregnant, the
numbness will disappear after the baby is born. Treating any of
the conditions mentioned above (arthritis, diabetes, low levels
of thyroid hormones, hormonal changes associated with menopause,
broken or dislocated bones in the wrist) should also bring relief
to your CTS.
Aspirin or other over-the-counter
pain relievers such as Aleve, Motrin or Tylenol may relieve the
pain. Your doctor should first prescribe a wrist splint to help
hold the wrist in an upward position. This position is important
because it allows the nerve the room it needs. The splint may be
worn round-the-clock or only at night depending on what gives you
the most comfort. Elevate your hands when you sleep so that fluid
drains back down your arm and decompresses the tunnel through which
the nerve is passing. Strap an ice pack to your wrist for 10 - 20
minutes; place your wrists under a cold running tap or soak in an
ice water bath to relieve the inflammation. You may add a few tablespoons
of salt to the water bath. A therapist may do paraffin or hot wax
bath and wrist massage. If you are not feeling better after a few
weeks, your doctor may recommend a cortisone injection. The purpose
of the cortisone is to decrease the swelling around the tendons.
It is like putting the aspirin right into the wrist.
Some people get better after one injection. Others might require
a repeat. Cortisone should not be used frequently because it may
cause the tendons to breakdown. Vitamin B2 (riboflavin) and Vitamin
B6 (pyridoxine) supplements may be helpful especially if you have
a deficiency of the vitamin. However excess doses of Vitamin B6
may also cause nerve damage. If these treatments do not work, then
surgery may be necessary. The procedure called a "release" involves
cutting the ligament forming the roof of the carpal tunnel to relieve
pressure on the median nerve. The operation is usually done on an
outpatient basis and successful in most cases. Before you consider
surgery, make sure you've made changes in the work place and seen
a physical or occupational therapist to learn new ways to work or
play. Surgery may not be able to undo muscle or nerve problems brought
on by years of strain. Even after surgery, these changes will still
be necessary if you do not want your CTS symptoms to come back.
Call your Doctor
if making changes in the way you work or play doesn't seem to
help and the pain is sufficient to keep you awake at night.
