When someone complains about carpal tunnel, odds are they are a heavy coffee drinker. Coffee impacts vitamin B6 absorption, which is the real cause of carpal tunnel.
The condition is common and a result of repetitive motion. Typing on a keyboard all day is a common cause nowadays. I got mine before computers from using a chain saw for days on end cutting firewood, using other vibrating shop tools and riding a motorcycle. It got worse when I took a job one summer as a painter. Swishing that brush back and forth all day long finally forced me to get the surgery.
The surgery is corrective and one of the easiest things medical-wise, I have ever done. Easy peasy. The doc slits your wrist, cuts the restrictive band across the carpal tunnel and sews you back up. I heals quickly and I was back to work after both surgeries after a day or two.
