Jane was an office worker, who always complaints about sore neck. She needed to stare at her computer for a long time to deal with a large amount of work.
She felt that her working desk and chair may be wrong or not suitable for her, because she got more and more pain during working. But when she was in her day-off time, she might just feel some stiffness but no obvious pain in her neck. Sometimes she put a heat pad on her neck and shoulder, trying to relieve some soreness.
