What is already known on this subject? Sickle cell disease (SCD) has an impact on all aspects of a person's life (Edwards et al., 2005, International Journal of Behavioral Medicine, 12, 171). Strickland , Jackson, Gilead, McGuire, and Quarles (2001, Journal of the National Black Nurses' Association, 12, 36) suggest that one of the crucial factors in determining quality of life for those with SCD is the severity, timing and number of painful sickling episodes. Exacerbations of pain are also cited as explanation for the majority of medical contacts for people with SCD (McClish et al., 2009, Pain, 145, 246). The majority of research focuses on the consequences of pain in terms of handicap, and its impact on emotional well-being, relationships and the need for medication/hospital treatment (Booker et al., 2006, Chronic Illness, 2, 39; Weisberg et al., 2013, Journal of Hospital Medicine, 8, 42) rather than how SCD patients experience and understand their pain. However, the actual nature of pain experience in SCD is poorly understood and sub-optimally managed (Booker et al., 2006; Taylor et al., 2010, Journal of Pain and Symptom Management, 40, 416). What does this study add? The experience of SCD pain is indescribable without the use of analogy, as it is unbearable, agonising, constant, inescapable and without limit. Difficulty describing pain creates a perception of being misunderstood or minimized by professionals. Personification of pain is often employed by patients to attempt to form a relationship with pain. Current pain measures used in clinical practice are inadequate at capturing the acute and chronic SCD pain experience.
