As a chiropractor myself I can tell you that repetitive motion can most certainly be a cause of irritation to both the vertebrae themselves and possibly their surrounding tissue (including nerves.) I have many patients who suffer from repetitive motion injuries...carpenters, factory workers, fork-lift drivers..the list goes on and on. Our body is very good at adapting to the positions we put it in and the motions we put it through but often that comes at a price. While I can't say for sure if chiropractic care would benefit you I would recommend you get your neck checked out. Chiropractors vary wildly in technique and ability and as such I further recommend you select one thoughtfully. If you would like to PM me with your location I would be happy to see if I can refer you to someone in your area.
Hope that helped.
