Just out of curiosity, which hand was it, what were the symptoms? About a year ago I noticed shooting pains in my hand and wrist usually when doing motions such as opening a car door or lifting a plastic bag of groceries (things that pulled the fingers length wise). I also noticed it was only on my left hand, the same side as I usually wore my watch. I wear a dive watch all the time, eiter a dress or working model. If you look at a dive watch, most have a huge crown (well, compared to normal watch) that sticks out from the right side.
This large crown was digging into the nerve junction between the second and third fingers, after typing all day where the watch pushed on the nerves there all day (I do computer work and write books, articles and such) it would leave me in agony.
I switched the watch to the right hand, the symptoms went away, and I haven't had any problems since. It seems to be a similar situation to guys with large wallets in the rear right pocket of their jeans....causes the sciatic nerve to flare up, move the wallet, the symptoms dissappear.
Just a word to the wise in case a Doctor gets a bit cut happy...look to other causes before doing a surgery.
