Sore Thumb Help For CrackBerry Addicts
When I got my first BlackBerry 8700, it took awhile for my right thumb to adjust to the constant scrolling and clicking. After months of use, my poor thumb was taking the brunt of its constant attachment to the scroll wheel. Thankfully the geniuses over at Crave have informed us that there's still hope!
According to My: Tech News, the New York spa Graceful Services is just one of many spas starting to offer BlackBerry finger massages. We know that typing causes Carpal Tunnel Syndrome in the wrist, so do you think repeated BlackBerry use will cause a chronic thumb pain called the Gamer's Thumb Syndrome?
. . .I use the Pearl but I could sure use a thumb massage anyway !
