Sickle Cell Pain: Understanding Causes and Improving Care

What is it about?

This article provides an overview of pain in sickle cell disease (SCD), including both acute vaso-occlusive pain and chronic pain that can persist over time. It explains that SCD pain is caused by more than blocked blood flow alone. Inflammation, nerve-related changes, and altered pain processing in the nervous system can also contribute to how pain develops and is experienced. Psychological, social, and environmental factors may further influence pain severity and its impact on daily life. The article also reviews current and emerging approaches to pain management, including physical and psychological therapies, pharmacologic and disease-modifying treatments.

Why is it important?

Pain is one of the most common and burdensome complications of SCD and a major reason for emergency department visits and hospitalizations. Despite its importance, many approaches to pain management are supported by limited or low-certainty evidence. This article highlights advances in understanding the biological and psychosocial factors that contribute to SCD pain, including findings from neuroimaging and quantitative sensory testing that suggest changes in how the nervous system processes pain. Recognizing these different pain mechanisms may help clinicians move beyond a one-size-fits-all approach and toward more individualized, multidisciplinary care that improves function and quality of life.
