Rationale
1. There is extensive literature showing comorbidity between chronic pain and depression, their bidirectional dependency and central nervous system linkages.
2. The category has been infrequently researched as a discrete diagnosis
3. Pain experts do not use the category
4. Assigning a Chapter V diagnosis to a small subset of chronic pain patients is highly arbitrary
5. Assigning a Chapter V diagnosis to a small subset of chronic pain patients presumes, or may be understood to presume, that there is a whole class of chronic pain patients for whom physiological factors are irrelevant.
