Carpal tunnel syndrome occurs when a nerve that runs into the hand from the lower arm becomes squeezed at the wrist.
The National Institute of Neurological Disorders and Stroke mentions these common symptoms of carpal tunnel syndrome:
- Having a tingling sensation or numbness in the thumb, palm or nearby fingers on one hand or both.
- Having fingers that feel swollen, even with no visible swelling.
- Having pain that affects one or both hands or wrists.
- Having difficulty moving the fingers.
- Having symptoms that first appear at night, then during the day.
- Having a weak grasp or grip.
Health Tip: At Risk of Carpal Tunnel Syndrome?
Carpal tunnel syndrome involves swelling of a nerve in the wrist that extends into the hand. It can cause pain and weakness, and is typically caused by repetitive motions over a long period of time.
The U.S. National Library of Medicine says these activities may cause carpal tunnel syndrome:
- Typing at a computer, especially if the workstation is not set up correctly.
- Working on an assembly line.
- Using vibrating tools or hand tools.
- Playing certain musical instruments.
