The association between pain and stress is an old one, but still it is not really clear who comes first. Pain induces stress, and stress induces pain. Pain is part of our homeostatic system and in this way is an emotion, i.e., it tells us that something is out-of-order (control), and emotion drives our behavior and one behavior is stress response. Stress comes from ourselves: the imagination we have or would like to have of us, from the image others give of us, from the goals we assume it is necessary to reach for our well-being or the goals others want us to fulfill. Stress comes from our social condition and the condition we would like, stress comes from dangerous situations we cannot control. Headache easily fits in the picture.
疼痛和压力之间的关系由来已久，但仍不清楚两者究竟谁先出现。疼痛会引发压力，而压力也会引发疼痛。疼痛是我们体内平衡系统的一部分，因此也是一种情绪，也就是说，它告诉我们有些事情失去了控制（失调），而情绪则会驱使我们的行为，其中一种行为就是应激反应。压力来自我们自身：我们的想象或希望、他人对我们的看法、我们为了自身幸福或他人希望我们实现的目标而设定的目标。压力来自我们的社会地位和我们想要的地位，来自我们无法控制的危险情况。头痛很容易符合这一情况。
