Neck pain can be caused by poor posture. Forward flexion of the neck can be exacerbated by electronics use, computer use, reading and hobbies such as sewing and knitting. Excessive forward flexion of the neck or anterior carriage can contribute to increase in headaches and even numbness and tingling to the hands.
The chin poke exercise is one exercise that can help relieve neck pain:
Roll your shoulders back
Tuck your stomach in
Bring your chin up and gaze forward without looking up or down
Draw your chin back and neck back
