Trauma
Any form of direct trauma, such as hitting the ground on your golf swing, can cause injury to the wrist and hand. Improper hitting or punching techniques can cause wrist/hand injuries and possibly hairline fractures.
Head & Neck Problems
The most common cause of pain in the wrist and hand is the position of your neck. The nerves that power your hand come from your neck. When you’re sitting at your computer, your neck may be in an improper position and this may compromise those nerves. When those nerves are compromised, you may experience traveling pain in your hands, and you could make your hands vulnerable to repetitive stress injury.
