Axial spondyloarthritis · Common questions
Straight answers to the questions people most often ask about axial spondyloarthritis, including why a normal X-ray does not rule it out and why diagnosis so often takes years.
No. A normal X-ray does not rule out axial spondyloarthritis (axSpA). In the earlier form, called non-radiographic axSpA, the inflammation is present but has not yet caused the bone changes that show up on plain X-rays. An MRI scan can often show the active inflammation that an X-ray misses, and the diagnosis also rests on your symptoms, examination, and sometimes a blood test (HLA-B27).
So being told your X-ray is clear is not the end of the story. The axSpA guide explains this in more detail.
Long delays are, unfortunately, common in axSpA, often several years from the first symptoms. Back pain is extremely common and usually not inflammatory, the early X-rays are often normal, and the pattern that points to axSpA, such as pain that improves with movement and wakes you in the second half of the night, is easy to miss. Many people are told it is ordinary back pain for a long time.
That delay is real and frustrating, and it is not a reflection on you. Getting the pattern recognised is what changes things, which is why describing exactly how your back behaves matters so much.
It is very common, and patients describe it clearly: being made to feel like a difficult patient, or having pain put down to stress or something psychological, sometimes for years. That experience is real and it can leave a lasting mark on how you feel about seeking care.
What helps now is a clear account of your symptoms over time. The more specific you can be about the pattern, the easier it is for your team to act on it. You deserve to be believed and followed until things are clear.
Exercise. In axSpA, regular exercise is not just helpful, it is a core part of treatment, alongside medicines, not instead of them. The right programme keeps the spine and joints mobile, maintains posture, and eases stiffness, and stopping moving tends to make things worse.
We have a dedicated axSpA exercise programme covering posture, mobility, and strength, with a link to the NASS Back to Action programme.
Morning stiffness and periods of flare are typical of axSpA. Keeping up gentle movement and your exercise programme, even when stiff, usually helps more than resting completely, and a warm shower or gentle mobility work in the morning can ease the start of the day. Keep any prescribed medicines going unless told otherwise.
If a flare is severe or not settling, or comes with new symptoms, contact your team. You can track your symptoms over time with the BASDAI and BASFI trackers.
Fatigue in axSpA is often described as overwhelming and different from ordinary tiredness. It is a genuine part of the inflammatory disease, can be worse when the disease is active or sleep is disturbed by pain, and deserves to be taken seriously rather than brushed off.
Treating the inflammation, staying active, and sorting out sleep all help. See sleep and fatigue.
