In carpal tunnel syndrome, the median nerve in your wrist gets pinched. This typically causes numbness and tingling in the fingers at night, or while talking on the phone or holding a newspaper.
Those don’t fit the typical aches and pains we see with repetitive motion injuries.
But while typing and texting don’t cause carpal tunnel, they can make symptoms more noticeable.
No one really knows what causes this syndrome. But three things increase your risk:
The good news is that mild carpal tunnel syndrome often goes away after you wear a wrist splint at night for a few weeks. NSAIDs and acetaminophen help to relieve any pain.
A cortisone injection into the carpal tunnel sometimes helps as well.
More serious cases may require surgery. The key is to seek help before you develop round-the-clock numbness. At that point, even surgery won’t completely resolve your symptoms.
