You are very welcome, Gene.
The condition, occasionally may go away spontaneously, but usually need some treatment. You may go to either Chiropractor or an Orthopedist as a first step. Hot fomentation can be in the form of;
1) Heating pad on neck or
2) Warm wet compresses (towel dipped in warm water and applied to stiff neck).
Your work posture can be the causative as you mentioned.
It is pleasure and privilege assisting you.
