Neck and shoulder pain arise most commonly in the workplace and during frequent travel, due to incorrect posture, mental stress, and fatigue. It is among the most difficult types of pain to treat with heat therapy. Most heating pads for the neck just tend to slip off or require the person to be immobile.
