Ankylosing Spondylitis Red Flags: 3 Warning Signs Your Chicago Rheumatologist Wants You to Know

Do you wake up stiff and achy every morning — and it takes over an hour to loosen up? Many people brush this off as “just getting older” or blame a bad mattress. But for some patients, this could be a sign of ankylosing spondylitis (AS), a form of inflammatory arthritis that affects the spine.

At Chicago Arthritis, our team specializes in identifying these symptoms early so patients can get the right treatment before joint damage progresses. Here’s what to know if you’re dealing with unexplained back pain.

What Is Ankylosing Spondylitis?

Ankylosing spondylitis is a type of autoimmune, inflammatory arthritis that primarily affects the spine and sacroiliac joints (where the spine meets the pelvis). Unlike ordinary back pain from overuse or injury, AS is driven by inflammation — meaning it behaves very differently and requires a different treatment approach.

3 Key Red Flags to Watch For

If you’re dealing with back pain, ask yourself these three questions:

1. Do You Have Significant Morning Stiffness?

• Stiffness that lasts more than an hour after waking up is a major clue.
• Ordinary mechanical back pain usually loosens up quickly. Inflammatory back pain does not.

2. Is Your Pain Worse with Rest and Better with Movement?

• Pain that flares up first thing in the morning or after sitting still
• Pain that actually improves once you start moving around
• This pattern is a hallmark of inflammatory back pain, unlike typical arthritis or muscle strain, which often worsens with activity.

3. Did Your Back Pain Start Before Age 30?

• AS commonly begins in young adults, often in their late teens through 20s.
• New back pain in this age group — especially if it’s persistent — deserves closer evaluation.

Other Warning Signs to Mention to Your Doctor

Beyond the three big red flags above, let your primary care doctor or rheumatology specialist know if you have any of the following:

• Red, painful eyes (uveitis)
• Skin rashes resembling psoriasis
• A personal history of other autoimmune conditions
• A family history of autoimmune disease

These associated symptoms can strengthen the case for further testing and a referral to a rheumatologist.

Why Early Diagnosis Matters

Inflammatory back pain conditions like ankylosing spondylitis can, over time, lead to permanent changes in the spine if left untreated. The good news? With early diagnosis, patients have access to a wide range of effective options, including:

• Targeted anti-inflammatory and biologic medications
• Physical therapy and movement-based treatment plans
• Regenerative medicine approaches, such as PRP therapy, to support joint and tissue health
• Comprehensive chronic pain management strategies

When Should You See a Rheumatologist?

If you’re experiencing prolonged morning stiffness, pain that’s worse with rest, or back pain that started before age 30, it’s time to talk to a specialist. A Chicago rheumatologist can run the right tests — including bloodwork and imaging — to determine whether your symptoms point to ankylosing spondylitis or another form of inflammatory arthritis.
