An estimated 3.3 million individuals in the U.S. are living with spondyloarthritis1,2 (SpA), an inflammatory disease affecting the spine, and in some people, the joints of the arms and legs, skin, intestines, and eyes. An underdiagnosed condition, most people with SpA first experience symptoms in their 20s or 30s but typically wait as many as 10 years between symptom onset and SpA diagnosis. *
