Certainly Hypermobility EDS (type III). Probably for some people with Classical EDS (type I and II). Back pain with scoliosis in Kyphoscoliosis EDS (type VI). Joint pain and early degenerative arthritis are part of EDS type VII. Answered by Peter Byers, MD
"The present study indicates that chronic, frequently debilitating pain of early onset and diverse distribution is a constant feature in most individuals affected with different types of EDS." Functional impacts of chronic pain impact sleep, sexual functioning, social relations, physical activity, school and/or job functioning. Although individuals with Vascular EDS seem to have a substantially smaller number of painful locations as compared to individuals with Classical and Hypermobility Types. Because EDS is relatively rare, systematic study of pain in this population or of its relief has not been performed. EDS should be considered in the differential diagnosis of chronic musculoskeletal pain." [Sacheti A. et al.: Chronic Pain is a Manifestation of the Ehlers-Danlos Syndrome.

“Chronic pain is a well-established and cardinal manifestation of EDS and it is common for pain to be out of proportion to physical and radiological findings. The etiology of EDS pain is not clearly understood, but some of the likely causes include muscle spasm (tender points are sometimes present) and degenerative arthritis; neuropathic pain is also common.” [EDNF's Pain Management Medical Resource Guide available elsewhere on this site.]
"Chronic pain, distinct from that associated with acute dislocations or advanced osteoarthritis, is a serious complication of the condition and can be both physically and psychologically disabling."

"The results of this study show that 1) chronic pain in EDS is highly prevalent and associated with regular use of analgesics; 2) pain is more prevalent and more severe in the hypermobility type than in the classic type; 3) pain severity is correlated with hypermobility, dislocations and previous surgery; 4) pain is correlated with low nocturnal sleep quality; and 5) pain contributes to functional impairment in daily life, independently of the level of fatigue. From this large cohort of EDS patients, we conclude that pain is common and severe in EDS. Pain is related to hypermobility, dislocations, and previous surgery and associated with moderate to severe impairment in daily functioning… Our findings suggest that pain is a very common and severe symptom in this group of EDS patients. It is related to dislocations, sleep disturbances and moderate-to-severe impairment in daily functioning. Therefore, treatment of pain should be a prominent aspect of clinical management of EDS."
