The symptoms of carpal tunnel syndrome usually develop gradually. Symptoms often improve if you stop or change an activity that is helping to cause the condition.
Most mild cases of carpal tunnel syndrome get better with treatment. Usually there is no permanent damage to the median nerve. Your symptoms may improve by themselves when:
Fluid buildup decreases, such as after pregnancy.
You change or stop the activity that has caused your carpal tunnel syndrome.
Other health problems that cause or contribute to your carpal tunnel symptoms improve.
Long-term carpal tunnel syndrome can cause:
A loss of feeling and coordination in the fingers and hand. The thumb muscles can become weak and waste away (atrophy).This can make it hard to grip or hold objects.
Permanent damage to the median nerve. You may have trouble using the hand.
