In this article, we consider the possible reasons and supporting evidence for the comorbidity of chronic pain conditions. To simplify the discussion, we primarily focus on the epidemiology of headache with other pain conditions, dividing studies into those based on children or adolescents and those based on adults. We consider exogenous and endogenous factors, and methodological challenges, in understanding whether and how 2 pain conditions may be related.
在本文中，我们探讨了慢性疼痛病症合并存在的可能原因及支持证据。为简化讨论，我们主要聚焦于头痛与其他疼痛病症的流行病学情况，将研究分为基于儿童或青少年的研究以及基于成人的研究。在理解两种疼痛病症是否相关以及如何相关的过程中，我们考虑了外源性和内源性因素以及方法学上的挑战。
