I have neck pain making it painful to raise my head. What should I do to get better? More information below.?

[Want2know]

When the neck does not hurt there is still pain at the base of my head on the right side where it extends out a little. I think I hurt it doing data entry and turning my head too far to the right. When I use my neck a lot the right side of my neck starts to hurt and it is painful to lift my head.
Do I need a neck brace? Do I need to avoid using the neck? Will I injure it more with use? I think the original injury happened at the base of my head when I turned my head too far to do data entry.
