Yes I know some excersises... Arm out stretched, palm down.Pull your fingers back towards your elbow and feel the stretch on the inside of your wrist. Then fingers down (limp wrist style) and push your fingers down and feel the stretch across the top of your wrist. Then shake out and relax. You may have tendonitis. I've had carpal tunnel problems after giving birth to numerous babies, and shaking cocktail shakers doesn't help at all. I get numb fingers but the feeling comes back if I dangle my arms and shrug my sholders.

Keep up the excersises, they really do work. Don't ask for surgery.
