Ankylosing spondylitis (AS) is arthritis that primarily affects the spine but can also impact other joints. Recognizing the early signs of Ankylosing spondylitis is crucial for early diagnosis and treatment. Catching it early can help manage symptoms and prevent severe complications, such as permanent joint damage and loss of mobility.
In this article, we’ll explore the early symptoms of Ankylosing spondylitis that you shouldn’t ignore, treatment options, and tips to manage the condition effectively.
1. Unexplained Lower Back Pain
One of the most common early symptoms of AS is persistent lower back pain that doesn’t seem to have an obvious cause. The pain often starts at the bottom of the spine, where the sacrum (a large, triangular bone) meets the pelvis. Unlike back pain from an injury, AS pain often feels better when you move around or get active but may worsen when you’re at rest, especially after a night’s sleep.
This type of pain usually doesn’t go away over time, and you may experience periods of pain and stiffness that come and go. It’s essential to seek medical advice if you have unexplained lower back pain that doesn’t improve with regular stretching or over-the-counter pain relief.
2. Stiffness and Pain in Other Body Parts
As Ankylosing spondylitis progresses, you might experience stiffness and pain in other parts of your body. This includes the heels, especially the Achilles tendon, and other joints, such as the wrists, ankles, knees, and shoulders. The chest may also feel tight, and deep breathing might become uncomfortable due to pain around the ribs and breastbone.
These symptoms may occur before the back pain becomes severe, so it’s important to pay attention to body aches and stiffness. If you notice pain in places other than your back, it could be an early sign of AS.
3. Pain that Comes and Goes but Eventually Worsens
At first, the pain may be intermittent, flaring up and then decreasing in intensity. However, as the disease progresses, you may notice that the pain becomes more persistent, affecting more parts of your spine and joints. It’s not just the lower back anymore—it may extend to the upper spine, causing difficulty with movement and flexibility.
Initially, you might feel better after being active or stretching, but this pain might not entirely go away over time, even with movement.
4. Pain that Improves with Movement
One of the hallmarks of AS is that the pain tends to improve with physical activity. This is the opposite of typical back pain caused by an injury, which often worsens with movement. If your pain improves after a walk, stretching, or light exercise, it could be a sign that you’re dealing with AS.
Unlike typical back pain, which may respond to rest, the inflammation in AS is better managed with regular movement and physical therapy.

5. Enthesitis (Inflammation at Tendon and Ligament Attachment Sites)
Enthesitis refers to inflammation where tendons and ligaments attach to bones, and it’s another common early symptom of AS. You may experience pain in the Achilles tendon and other areas like the heels and hips. Swelling at these tendon attachment sites is often a red flag for AS, mainly if it’s not linked to a specific injury.
Attention to these tender spots is crucial, as early treatment can prevent long-term damage and pain.
6. Reduced Range of Motion
As the condition progresses, you may notice that your spine becomes stiffer and your range of motion decreases. This means bending over, twisting your torso, or even looking up at the sky might be more challenging. These restrictions can affect your daily activities, so seeking help is essential if you’re experiencing noticeable difficulty moving your back or neck.
Physical therapy can significantly improving mobility, even in the early stages of Ankylosing spondylitis.
7. Mild Swelling in Joints
Swelling in the knees, ankles, wrists, and shoulders can also be an early symptom of AS. This swelling is different from the typical swelling that happens after an injury because it’s usually accompanied by stiffness and a dull, aching pain. If you notice any of these joint symptoms, it’s worth checking with a healthcare provider, especially if you also experience lower back pain.
8. Chest Pain or Pleuritis
If you start to experience chest pain or difficulty breathing, especially with deep breaths, it might be a sign that your AS has progressed to affect your rib joints. This condition is called pleuritis, where inflammation of the lungs or their lining causes pain in the chest and makes it hard to breathe deeply.
If you experience chest pain or shortness of breath along with other symptoms of AS, don’t hesitate to consult a doctor right away to prevent complications.
9. Fatigue and Systemic Symptoms
Ankylosing spondylitis often leads to fatigue. The inflammation your body is fighting can use up much energy, leading to tiredness that doesn’t improve with rest. You may also experience mild fever or a general sense of being unwell, especially during flare-ups. If this fatigue is accompanied by other symptoms of AS, such as joint pain or back stiffness, it’s worth talking to your doctor.
10. Bowel Issues (IBD-related)
A significant number of people with AS also experience symptoms of inflammatory bowel disease (IBD), such as Crohn’s disease or ulcerative colitis. Symptoms might include diarrhea, bloating, cramping, or even blood in the stool. If you notice these symptoms along with the signs of AS, it’s essential to inform your doctor so that appropriate care can be provided.
11. Sleep Disturbances
Because of the pain, many people with AS experience difficulty sleeping. You may find that the pain worsens when you’re lying down, especially in the early hours of the morning. This can interfere with your ability to get restful sleep, which can then lead to more fatigue and difficulty managing the symptoms of AS.
If you wake up in the middle of the night with back pain or stiffness, it’s time to talk to your doctor.
12. When to See a Doctor
If you’re experiencing any combination of these symptoms, especially if they persist or worsen over time, seeking medical advice is crucial. Early diagnosis can help prevent the progression of the disease and minimize joint damage. You should particularly reach out to a doctor if:
- You experience persistent lower back pain or stiffness
- Joint pain and swelling don’t go away with rest
- You have difficulty breathing or chest pain
- You notice any neurological symptoms, like leg weakness or numbness
Treatment Options for Ankylosing Spondylitis
While there is no cure for Ankylosing spondylitis, effective treatments can help manage the condition. Early treatment is critical to slowing disease progression and alleviating pain.
Here are some treatment options:
- Nonsteroidal Anti-Inflammatory Drugs (NSAIDs): These over-the-counter medications, such as ibuprofen and naproxen, can help reduce pain and inflammation.
- Disease-Modifying Anti-Rheumatic Drugs (DMARDs): These medications can help slow disease progression.
- Biologic Medications: If NSAIDs don’t provide relief, biologics like TNF inhibitors (e.g., Humira, Enbrel) or IL-17 inhibitors (e.g., Taltz) might be prescribed.
- Physical Therapy: A physical therapist can guide you through exercises that improve your range of motion, flexibility, and overall spinal health.
- Corticosteroids: These may be used to control inflammation in flare-ups.
Tips to Manage Ankylosing Spondylitis
Managing Ankylosing spondylitis involves more than just medication.
Here are some helpful tips:
- Exercise Regularly: Regular physical activity can help with pain relief, flexibility, and maintaining mobility. Focus on exercises that strengthen muscles, improve flexibility, and promote good posture.
- Eat an Anti-inflammatory Diet: Focus on whole foods like leafy greens, colorful vegetables, and omega-3-rich foods while avoiding processed foods high in sugar and unhealthy fats.
- Maintain Good Posture: Pay attention to how you sit, stand, and sleep. Ergonomic adjustments can reduce strain on your spine.
- Manage Stress: Stress can trigger flare-ups, so practices like yoga, meditation, and breathing exercises can be very helpful.
- Quit Smoking: Smoking can worsen AS, so quitting is essential for managing the condition and preventing flare-ups.
Conclusion
Ankylosing spondylitis can be challenging, but with the proper treatment and lifestyle changes, you can manage the symptoms and improve your quality of life. Early recognition of the symptoms is key to controlling the disease, so don’t ignore persistent back pain, stiffness, or other warning signs. If you suspect you may have AS, reach out to your doctor for a proper diagnosis and treatment plan.
