I sit at a computer all day and have used a ball for about 2 years now. Some days, or parts of days, I do revert back to my regular chair for a change. I don't have any existing back/neck issues to compare before or after. What I like about the ball is I feel I move a lot more, meaning I'm not in a constant static position. You can get a ball at walmart or target quite inexpensively, so perhaps it is just worth a try?
