What Is Nr-axSpA?
What Is Non-Radiographic Axial
Non-radiographic axial spondyloarthritis, or nr-axSpA (pronounced N-R-Ax-Spa), is a chronic inflammatory condition. It’s characterized by active inflammation of the spine and sacroiliac (SI) joints, which are the joints that connect the lower spine and pelvis.
Nr-axSpA belongs to the axial spondyloarthritis (axSpA) family of inflammatory conditions. These conditions affect the spine and SI joints, but signs and symptoms can occur in other parts of the body. Another condition classified in the axSpA family is ankylosing spondylitis (AS). Many of the signs and symptoms of nr-axSpA and AS overlap, but a rheumatologist can distinguish between these two conditions using x-ray imaging, a key diagnostic test, as well as other tests like blood tests.

Not All Back Pain Is The Same
Because back pain is common, many people attribute the symptoms of nr-axSpA to mechanical conditions in the structure of the back (eg, dislocation, pinched nerve, slipped disc, or muscle strain). However, since the pain from nr-axSpA is caused by inflammation, it should be treated differently.
Signs of inflammatory back pain related to nr-axSpA:
- Pain that lasts 3 months or longer
- Pain that goes away with exercise and activity
- Pain while sleeping
- Age of onset <45 years
Additional signs and symptoms:
- Morning stiffness
- Reduced mobility
- Limitations at work and home
Some people with nr-axSpA can experience symptoms that are more widespread, such as:
- Swelling around the joints
- Abdominal pain
- Sensitivity to light
Nr-axSpA in Women
Women, over half of the nr-axSpA population, may experience symptoms differently than men. Women tend to have pain that is more widespread, which can result in a diagnostic delay. On average, an nr-axSpA diagnosis takes more than a year longer in women than in men.
Nearly 1.7 million individuals in the US live with nr-axSpA
You Don’t Have Time
For Chronic Back Pain
Non-radiographic axial spondyloarthritis can start slowing you down even before you get out of bed; it’s hard to start the day with stiffness, decreased mobility, and debilitating chronic back pain. You may be tired of calling in sick and canceling plans with friends. In addition to the pressure of commitments, the list of things to do around the house is getting longer.
Feeling discouraged and misunderstood with nr-axSpA is warranted. Talking to a rheumatologist can help you take control of your condition.
Download our Doctor Discussion Guide to prepare for your appointment with a rheumatologist. Through open conversation with your doctor about how your nr-axSpA symptoms are affecting you physically and emotionally, together you can decide the best treatment option for you.
Chronic Back Pain
Prolonged by Misdiagnosis
It’s a long road to answers for many people living with inflammatory back pain. On average, it takes 5 to 8 years for those with nr-axSpA to receive an accurate diagnosis.
Since the awareness for nr-axSpA is low, it is often misdiagnosed. Most back pain conditions are mechanical-related, and it’s difficult for many physicians to discern the difference between mechanical pain (eg, muscle strain, slipped disc or pinched nerve) and inflammatory pain. Nr-axSpA is often misdiagnosed as fibromyalgia (a neurological condition) since chronic pain in the back and other parts of the body is often a feature of both conditions.
Misdiagnosis and visits to multiple specialists can be discouraging. However, being aware of the signs of inflammation and working with the right specialist can help uncover the cause. Trained to diagnose and treat inflammatory conditions, a rheumatologist is the best physician to evaluate you for nr-axSpA.
If x-rays do not show visible changes in your joints or spine, it could be nr-axSpA. Your rheumatologist may then recommend an MRI (magnetic resonance imaging) to detect inflammation. Additional tests in the diagnostic process may include, but are not limited to:
- Evaluation of medical history, including family history
- Laboratory tests for erythrocyte sedimentation rate (ESR) or C-reactive protein (CRP) levels, which indicate inflammation
- Certain blood tests for genetic markers, like HLA-B27
How To Treat Nr-axSpA
Non-steroidal anti-inflammatory drugs (NSAIDs) are often prescribed to people living with nr-axSpA. Pain relievers may help temporarily relieve pain, but they do not address the inflammation causing the symptoms.
CIMZIA (certolizumab pegol) is an anti-tumor necrosis factor (TNF) biologic. In people with nr-axSpA, the body makes too much TNF, causing immune cells to attack healthy tissue. This leads to inflammation and the symptoms you may be experiencing. By working to block these extra signals to immune cells, CIMZIA treats nr-axSpA where it starts, inside the body.
CIMZIA is the first and only therapy of its kind for nr-axSpA* proven to improve symptoms and disease activity over time.

In addition to CIMZIA, there are other ways to help manage the symptoms of nr-axSpA:
- Exercising regularly can help reduce pain and improve flexibility in those with nr-axSpA.†
- Keeping a food journal can help uncover whether certain foods are causing your symptoms to worsen, since diet and nutrition can make a difference.
- Reducing stress with meditation or yoga can be beneficial, as stress and anxiety can make it difficult to manage nr-axSpA symptoms and may cause them to worsen.
†Be sure to check with your doctor before increasing physical activity or beginning any new exercises.
