In general, RMIs are caused by repeated movements that involve:

•  Drilling or hammering.

•  Lifting.

•  Pushing or pulling.

•  Squeezing.

•  Twisting.

•  Wrist, finger, and hand movements.

For Carpal Tunnel Syndrome (CTS)

Repeated motions, typing vibrations, etc. cause swelling of the tendons inside the carpal tunnel. This is the narrow tunnel in the wrist. The swelling puts pressure on the nearby nerves.

For Carpal Tunnel Syndrome (CTS)

This is easier to treat and less likely to cause future problems if it is found early. Women are more likely to get CTS than men, because their carpal tunnel is usually smaller. Once diagnosed, CTS can be treated with:

•  Preventing further damage.

•  Wearing a wrist brace, splint, etc. as advised. It may need to be worn while you sleep and during the day.

•  Over-the- counter medicines to reduce pain and swelling. Examples are aspirin, ibuprofen, and naproxen sodium.

•  Physical therapy.

•  Occupational therapy.

•  Cortisone shots in the wrist area.

•  Surgery, if needed.
