Not a real devil. Not the kind from religion or stories. I mean the kind only someone with chronic pain understands: invisible, patient, quiet when it wants to be, violent when it wakes up.
For a long time, I did not know its name.
I only knew the pattern.
If I sat too long, it could wake up. If I ignored stiffness, it could wake up. If I ate carelessly, slept badly, worked under too much stress, pushed my body too hard, or rested in the wrong way, it could wake up.
And once it woke up, it was very hard to put it back to sleep.
Eventually, I learned its name.
Ankylosing spondylitis.
Even the name felt too clinical for something that had taken up so much space in my life. This was never just “back pain” for me. It was my neck locking so badly I could not turn properly. It was losing strength in my legs until walking became difficult. It was the humiliation of simple things becoming impossible. One of the worst memories I have is my wife tying my shoelaces because if I tried to bend forward, the pain would punish me.
That moment stayed with me. Not because of the shoelaces. Because of what it showed me.
I saw what ankylosing spondylitis could take from me if I did not take it seriously. It was not an idea anymore. It was sitting in front of me, challenging me, showing me a version of life where I could lose freedom one small movement at a time.
That was when I understood the deal. If I wanted to live, really live, I had to become smarter than this disease. More disciplined than it. More strategic than it.
I had to learn how to keep the devil asleep.
The Pain That Behaves Backwards
The first thing I wish I had understood is that AS pain often behaves backwards.
Most people think back pain means the body wants rest. You lie down, take it easy, wait, and hope the pain fades. But inflammatory back pain can do the opposite.
It can be worse after rest. Worse after sleep. Worse after sitting. Then, strangely, it can improve when you move.
Experts describe inflammatory back pain with features such as gradual onset, younger age at onset, improvement with exercise, no improvement with rest, and night pain that improves after getting up[1]. Primary-care guidance on axial spondyloarthritis also highlights morning stiffness, alternating buttock pain, improvement with exercise rather than rest, and good response to anti-inflammatory medication[2].
- Do I wake up stiff?
- Does the stiffness last more than 30 minutes?
- Is it worse after sitting or sleeping?
- Does movement help more than rest?
- Does pain wake me in the second half of the night?
- Did this begin before age 45?
- Has it lasted more than three months?
- Do I feel deep pain in my lower back, hips, or buttocks?
If the answer is yes to several of these, do not just “wait and see.” Write it down. Bring it to a doctor. Ask whether this could be inflammatory back pain or axial spondyloarthritis.
The goal is not to diagnose yourself. The goal is to stop dismissing the pattern.
Why Waiting Is Dangerous
The most dangerous thing I did was wait. Not because I was lazy. Because I did not know what I was waiting on. I thought stiffness would pass like a pulled muscle. I thought pain was something to endure. I thought I was being strong.
But AS is not impressed by silent suffering.
Diagnostic delay is a major problem in axial spondyloarthritis. A systematic review and meta-analysis found a pooled mean diagnostic delay of 6.7 years between symptom onset and diagnosis[3]. That is not a small delay. That is years of pain, confusion, missed treatment, and sometimes preventable damage.
Part of the problem is that early AS can hide. X-rays may be normal early. Blood inflammation markers such as CRP or ESR may be normal. HLA-B27 can support the diagnosis, but it is not a yes-or-no answer. Some people with AS are HLA-B27 negative, and many people who are HLA-B27 positive never develop AS. NICE guidance specifically warns that axial spondyloarthritis can be present even when X-rays do not show sacroiliitis and even when HLA-B27 is negative[4].
So if your symptoms fit the pattern, one normal test should not end the conversation.
The story matters. The pattern matters. The right specialist matters.
What AS Actually Is
Ankylosing spondylitis is a chronic inflammatory disease that mainly affects the spine and sacroiliac joints, where the lower spine meets the pelvis. It can also affect other joints, tendon and ligament attachment points, the ribs, hips, eyes, skin, and gut[5].
The disease is part of a wider family called axial spondyloarthritis, often shortened to axSpA. Some people have visible structural changes on X-ray, historically called ankylosing spondylitis or radiographic axSpA. Others have symptoms and inflammation that may be visible on MRI but not yet on X-ray, called non-radiographic axial spondyloarthritis[4][6].
AS is not just back pain. It is immune-driven inflammation.
And when inflammation keeps burning around the spine and pelvis, it can cause pain, stiffness, reduced mobility, and in some cases structural damage or fusion over time. Not everyone develops severe fusion, and modern treatment can help many people control disease activity, but waiting and guessing is not strategy[6][7].
The Doctor Conversation That Changes Everything
Do not walk into the appointment trying to sound like a medical textbook. Walk in with the pattern.
- “I have had lower back, hip, or buttock stiffness for more than three months. It is worse in the morning and after rest. It improves when I move. Sometimes it wakes me at night. I am worried this may be inflammatory back pain or axial spondyloarthritis.”
- “I think I have ankylosing spondylitis.”
That sentence is powerful because it gives your doctor clinical clues, not just fear.
- “Do my symptoms sound like inflammatory back pain?”
- “Should I be referred to a rheumatologist?”
- “If my X-ray is normal, would an MRI of the sacroiliac joints be appropriate?”
- “Should we test HLA-B27, CRP, and ESR?”
- “What should I track before my next appointment?”
A prepared patient is not a difficult patient. A prepared patient helps the doctor see the signal through the fog.
The Four Pillars
Living with AS is not one action. It is a system. For me, the system became four pillars.
Not all four pillars do the same job. They are not interchangeable. You cannot replace medical treatment with diet. You cannot replace movement with medication. You cannot replace sleep and stress management with willpower. But together, they create a life where the disease has fewer places to hide.
The clinical foundation
Major recommendations for axial spondyloarthritis include education, exercise, NSAIDs when appropriate, monitoring, and advanced therapies such as TNF inhibitors, IL-17 inhibitors, and, in selected cases, JAK inhibitors when disease activity remains high[7][9].
This does not mean everyone needs the same medication. It means AS should be managed with a rheumatologist and monitored properly. For many people, medication is what makes movement possible — it quiets the biological fire enough for the rest of the system to work.
If your disease is aggressive, needing medication does not mean you failed. It means the disease is real.
How you protect function
Movement is not optional decoration. Exercise and physiotherapy are consistently recommended for AS. Cochrane evidence suggests that home-based or supervised exercise programs are better than no intervention[10][12]. But not all movement is equal — this is about intelligent movement, not punishing the body.
- Gentle spinal mobility & hip mobility
- Chest expansion and breathing
- Posture work
- Walking or low-impact cardio
- Strength training adapted to your body
- Flare-day movement that is smaller but not zero
On good days, you build capacity. On bad days, you keep the bridge open. A flare is not the day to prove your toughness.
Experiment, don't panic
Some AS communities talk about low-starch diets, often connected to theories about gut bacteria. The gut connection is a serious area of research[13], but the evidence for specific diets remains limited and inconclusive[14].
So the honest position: food may matter for you. Food is not proven to cure AS. A diet experiment should never replace medical care. Test it like a scientist — track a baseline, change one thing at a time, give it a defined window, judge the data honestly.
If the diet becomes so restrictive that it damages nutrition, mood, or social life, that is not healing. That is the devil wearing a wellness costume.
The command center
AS is not “in your head.” The inflammation is real. But the mind is still involved — not as the cause, as the command center. It decides whether you track or ignore, move or freeze, sleep or scroll, stop before stress becomes a storm.
People with AS have increased risk of depression and anxiety, and mental health should be treated as part of care, not as a character flaw[15].
For me, mental training meant learning to notice early warning signs before they became punishment: a shift in fatigue, restless sleep, a strange stiffness, a mood change, the quiet sense that something was beginning to turn. The goal is vigilance without fear.
Respect the disease without worshipping it. Pay attention without making AS the center of your identity. Build routines, but still live. Keep the devil asleep, but do not spend your whole life staring at its bedroom door.
The Flare Plan
A flare is when the disease turns the volume up. Pain rises. Stiffness thickens. Sleep breaks. Energy drops. The mind gets darker. The body becomes expensive to operate.
Your job during a flare is not to panic. Your job is to reduce fuel.
- Did I sleep badly?
- Did stress spike?
- Did I sit too long?
- Did I overtrain?
- Did I stop moving?
- Did I eat something that often causes trouble?
- Did I ignore early stiffness?
- Did I miss medication or change routine?
- Move gently, but do not go completely still.
- Use heat if it helps. Scale down exercise intensity.
- Protect sleep. Eat predictably. Reduce commitments where possible.
- Follow your medication plan from your clinician.
- Contact your doctor if the flare is severe, unusual, prolonged, or different from your normal pattern.
Red Flags: When Not to Wait
Most AS symptoms are part of the long game. Some are not.
- A painful red eye, light sensitivity, or vision changes — uveitis can require urgent assessment[16].
- New leg weakness, numbness, or loss of bladder or bowel control.
- Severe chest pain or trouble breathing.
- Fever or signs of serious infection, especially if you are on immune-modifying medication.
- Sudden severe back or neck pain after a fall, jolt, or trauma — especially in advanced or fused disease.

Solution-Focused Resources
Use resources that help you act, not just worry.
- DiagnosisNICE NG65 & NIAMS. NICE gives practical guidance on recognizing and managing spondyloarthritis in people over 16; NIAMS explains diagnosis, tests, and treatment in patient-friendly language.[4][5]
- Primary careThe Mayo Clinic Proceedings guide on recognizing axial spondyloarthritis explains the inflammatory back pain pattern in terms clinicians understand.[2]
- TreatmentThe ASAS-EULAR, ACR/SAA/SPARTAN, and 2025 British Society for Rheumatology recommendations show how specialists think about NSAIDs, biologics, targeted therapies, monitoring, and escalation.[7][9]
- MovementThe National Axial Spondyloarthritis Society and Spondylitis Association of America provide practical exercise resources designed for axSpA and AS.[11][12]
- Disease activityThe Spondylitis Association of America's BASDAI calculator helps you understand one common disease-activity tool used in AS.[17]
- CanadaThe Canadian Spondyloarthritis Association offers patient resources, guidebooks, and support for people living with spondyloarthritis.[18]
- DietBegin with evidence reviews, not influencers. Macfarlane et al. concluded that evidence on diet and AS is extremely limited and inconclusive — exactly why diet should be a careful personal experiment, not a universal cure.[14]
- EyesKnow the emergency rule: a painful red eye, light sensitivity, or vision change should be assessed urgently. NHS uveitis guidance and the SAA's uveitis resource are useful starting points.[16]
What I Wish I Knew Earlier
- I wish I knew that rest making pain worse was a clue.
- I wish I knew that morning stiffness was not just age, posture, or a bad mattress.
- I wish I knew that a normal X-ray did not always close the case.
- I wish I knew that HLA-B27 was important, but not destiny.
- I wish I knew that medication was not weakness.
- I wish I knew that movement was not optional.
- I wish I knew that food might matter, but food fear can become its own prison.
- I wish I knew that mental discipline was not motivational fluff — it was part of the daily architecture.
AS did not only teach me pain. It taught me strategy. It taught me that ambition without recovery is just self-destruction in a better suit. It taught me that discipline is not punishment. It taught me that the body whispers before it roars. It taught me that every small success matters.
Every walk.
Every stretch.
Every honest appointment.
Every careful meal.
Every night of sleep protected.
Every stress storm calmed before it becomes fire.
Every moment I choose discipline over denial.
The devil may not disappear. But it can be weakened. Through medicine, through movement, through food awareness, through mental training — through learning your body so well that you hear the whisper before the roar.
Not perfection. Not panic. Not pretending.
A life where the devil remains asleep.
