What can be done to prevent the condition?

Any underlying cause of CTS should be diagnosed and corrected. For example, medicine can be used to correct hypothyroidism.

Overuse of the wrist and fingers should be avoided. A small recovery time is needed to rest and lubricate the flexor tendons. Variety is the key. Workers whose motions are repetitious and prolonged are at risk. A mixture of activities, such as typing interspersed with filing, may help to rest the affected areas. Finding a new way to use the hand, by using a different tool, may help some individuals. Using the nondominant hand more often might help to relieve stress on the dominant extremity.

Computer workstations should be designed so that the wrists are well supported in a neutral position. Care should be taken to avoid striking the palm side of the wrist on hard surfaces. Special on-the-job equipment and training may be available.

Early identification of symptoms is important. Early symptoms, such as tingling in the fingers, may occur several hours after the aggravating activity has stopped. Making the connection between activities and symptoms is important. This gives the person a chance to correct working conditions. This may help to prevent further or worsening symptoms.

What are the long-term effects of the condition?

If carpal tunnel syndrome isn't treated, the hand may become weaker and number. Permanent numbness and weakness can result.

What are the risks to others?

Carpal tunnel syndrome is not contagious and poses no risk to others.
