Carpal tunnel syndrome occurs when a combination of health conditions and activities
puts pressure on the
median nerve as it passes through the
carpal tunnel in your wrist. This pressure leads to
tingling, numbness, pain, and/or weakness in parts of your hand and, sometimes,
up into your arm. Anything that decreases the amount of space in the carpal
tunnel, increases the amount of tissue in the tunnel, or increases the
sensitivity of the median nerve can lead to carpal tunnel syndrome.
Things that help cause carpal tunnel syndrome include:

which may contribute to carpal tunnel syndrome by affecting the blood flow to
the median nerve.
Carpal tunnel syndrome is a common work-related injury.
Work that requires forceful or repetitive hand movements, hand-arm vibration,
or working for long periods in the same or in awkward positions-especially when
combined with other health conditions-may cause carpal tunnel syndrome.
In some cases the cause of carpal tunnel
syndrome cannot be determined.
