During the physical exam, your doctor might ask you to bend in different directions to test the range of motion in your spine. He or she might try to reproduce your pain by pressing on specific portions of your pelvis or by moving your legs into a particular position. Also, your doctor might ask you to take a deep breath to see if you have difficulty expanding your chest.
X-rays allow your doctor to check for changes in your joints and bones, though the visible signs of ankylosing spondylitis might not be evident early in the disease.
An MRI uses radio waves and a strong magnetic field to provide more-detailed images of bones and soft tissues. MRI scans can reveal evidence of ankylosing spondylitis earlier in the disease process, but are much more expensive.
There are no specific lab tests to identify ankylosing spondylitis. Certain blood tests can check for markers of inflammation, but inflammation can be caused by many different health problems.
Your blood can be tested for the HLA-B27 gene, but most people who have that gene don't have ankylosing spondylitis, and fewer black people with the disease have the gene than do white people.
The goal of treatment is to relieve your pain and stiffness, and prevent or delay complications and spinal deformity. Ankylosing spondylitis treatment is most successful before the disease causes irreversible damage to your joints.
Nonsteroidal anti-inflammatory drugs (NSAIDs) — such as naproxen (Naprosyn) and indomethacin (Indocin) — are the medications doctors most commonly use to treat ankylosing spondylitis. They can relieve your inflammation, pain and stiffness. However, these medications might cause gastrointestinal bleeding.
If NSAIDs aren't helpful, your doctor might suggest starting a biologic medication, such as a tumor necrosis factor (TNF) blocker or an interleukin 17 (IL-17) inhibitor. TNF blockers target a cell protein that causes inflammation in the body. IL-17 plays a role in your body's defense against infection and also has a role in inflammation.
TNF blockers help reduce pain, stiffness, and tender or swollen joints. They are administered by injecting the medication under the skin or through an intravenous line.
The five TNF blockers approved by the Food & Drug Administration to treat ankylosing spondylitis are:
- Adalimumab (Humira)
- Certolizumab pegol (Cimzia)
- Etanercept (Enbrel)
- Golimumab (Simponi; Simponi Aria)
- Infliximab (Remicade)
Secukinumab (Cosentyx) is the first IL-17 inhibitor approved by the FDA for the treatment of ankylosing spondylitis.
TNF blockers and IL-17 inhibitors can reactivate latent tuberculosis and make you more prone to infection.
Physical therapy is an important part of treatment and can provide a number of benefits, from pain relief to improved strength and flexibility. A physical therapist can design specific exercises for your needs.
Range-of-motion and stretching exercises can help maintain flexibility in your joints and preserve good posture. Proper sleep and walking positions and abdominal and back exercises can help maintain your upright posture.
Most people with ankylosing spondylitis don't need surgery. However, your doctor might recommend surgery if you have severe pain or joint damage, or if your hip joint is so damaged that it needs to be replaced.

Lifestyle and home remedies
Besides seeing your doctor regularly and taking your medications as prescribed, here are some things you can do to help your condition.
- Stay active. Exercise can help ease pain, maintain flexibility and improve your posture.
- Apply heat and cold. Heat applied to stiff joints and tight muscles can ease pain and stiffness. Try heating pads and hot baths and showers. Ice on inflamed areas can help reduce swelling.
- Don't smoke. If you smoke, quit. Smoking is generally bad for your health, but it creates additional problems for people with ankylosing spondylitis, including further hampering breathing.
- Practice good posture. Practicing standing straight in front of a mirror can help you avoid some of the problems associated with ankylosing spondylitis.
Coping and support
The course of your condition can change over time, and you might have painful episodes (relapses) and periods of less pain (remissions) throughout your life. But most people are able to live productive lives despite a diagnosis of ankylosing spondylitis.
You might want to join an online or in-person support group of people with this condition, to share experiences and support.
Preparing for your appointment
You might first bring your symptoms to the attention of your family doctor. He or she may refer you to a doctor who specializes in inflammatory disorders (rheumatologist).
Here's some information to help you get ready for your appointment.
What you can do
Make a list of:
- Your symptoms, including any that may seem unrelated to the reason you made the appointment, and when they began
- Key personal information, including major stresses, recent life changes and family medical history
- All medications, vitamins and other supplements you take and their doses
- Questions to ask your doctor
Take a family member or friend along, if possible, to help you remember the information you're given.
For ankylosing spondylitis, basic questions to ask your doctor include:
- What's likely causing my symptoms?
- Other than the most likely cause, what are other possible causes for my symptoms?
- What tests do I need?
- Is my condition likely temporary or chronic?
- What's the best course of action?
- What are the alternatives to the primary approach you're suggesting?
- I have these other health conditions. How can I best manage them together?
- Are there restrictions I need to follow?
- Should I see a specialist?
- Are there brochures or other printed material I can have? What websites do you recommend?
What to expect from your doctor
Your doctor is likely to ask you questions, such as:
- Where is your pain?
- How severe is your pain?
- Have your symptoms been continuous or occasional?
- What, if anything, seems to worsen or improve your symptoms?
- Have you taken medications to relieve the pain? What helped most?
