I have also been Dx with Spondyloarthropathy (SpA). This is a common form of autoimmune, inflammatory arthritis and is well known to be associated with Inflammatory Bowel Disease. The process affecting the joints is very similar to that which causes our gut problems, but it is an entirely different entity. This is NOT Crohn's attacking the joints, but a separate complication.
Anyone suffering with joint or back pain should be evaluated by a Rheumatologist to investigate the possibility of Spondyloarthropathy (SpA). These include: Ankylosing Spondylitis, Psoriatic Arthritis, Reactive Arthritis, Enteropathic Arthritis, Juvenile Spondyloarthropathy and Undifferentiated Spondyloarthropathy.
At one time, these types of arthritis were commonly believed to affect mostly men and so the Dx of women is still often delayed by many years. It's important to find a Rheumy who is knowledgable about
SpA and can make the Dx and begin treatment. The good news for us is that often, the treatment for SpA is the same, or very similar, to those used for Crohn's. For instance, I'm using Humira every week and taking a low daily dose of pred, but these meds are prescribed by my Rheumy for my joints. They've also helped put my gut in order so that I'm just about
in remission.
