Does taking NSAIDs always relieve back pain in ankylosing spondylitis?


Hello, Dr.
Gao.
My son is 19 years old and has been diagnosed with ankylosing spondylitis for three years.
He has undergone relevant blood tests and MRI scans, and the rheumatologist confirmed the diagnosis.
Initially, his symptoms included pain in the buttocks, but now he takes Celebrex regularly and experiences minimal pain.
However, six months ago, he began to experience pain in his lower back (around the L4-L5 region).
Over the past six months, he has tried taking Voltaren for three weeks (one pill daily) without relief, followed by two weeks of Celebrex (one pill daily), which also proved ineffective.
He then stopped taking anti-inflammatory pain medications, opting to rely on exercise for relief, but he has been experiencing persistent mild pain without worsening.
He has also noticed that his symptoms tend to improve slightly in the afternoon compared to the morning (but only slightly).
During his follow-up appointment, the rheumatologist mentioned that this is a symptom of ankylosing spondylitis and advised him to continue exercising and minimize medication use.

I would like to ask Dr.
Gao: 1) Is it true that back pain from ankylosing spondylitis can be alleviated with NSAIDs combined with appropriate exercise? Are there cases of more severe ankylosing spondylitis back pain that cannot be managed solely with NSAIDs and exercise? 2) Over the past six months, we have wondered if this could be an exercise-related injury (such as from playing badminton), but even with reduced activity, his condition remains unchanged.
Does his symptom resemble an exercise injury? Is it difficult for a 19-year-old to recover naturally from an exercise injury after a period of rest? Note: In the past six months, he has had three blood tests, with CRP and ESR results of 0.2 and 39 on the first test, 0.4 and 56 on the second, and 0.9 and 22 on the most recent test.
Thank you, doctor.

Hello, thank you for your question.
Here are my responses:
1) Regarding the back pain from ankylosing spondylitis, is it true that taking NSAIDs combined with appropriate exercise will definitely relieve the pain? Are there cases of more severe ankylosing spondylitis where pain cannot be managed solely with NSAIDs and exercise? --> In principle, early-stage ankylosing spondylitis responds well to anti-inflammatory pain relievers.
We can even use the response of such patients to these medications to assess the accuracy of the ankylosing spondylitis diagnosis.
However, once the disease progresses over time, adhesions may develop, affecting the spinal structure, and at this point, the effectiveness of anti-inflammatory medications may diminish.
Therefore, early treatment and regular exercise to prevent joint adhesions are crucial.
2) Over the past six months, I have also wondered if this could be due to a sports injury (such as from badminton...), but even with reduced activity for a period, there has been no improvement or worsening.
Does my son’s symptoms resemble a sports injury? Is it difficult for a 19-year-old to recover naturally from a sports injury after a period of rest? --> If X-rays show no adhesions in the spine, and pain persists despite ongoing medication and exercise, further evaluation may be necessary to rule out the possibility of a sports injury.
It would be advisable to consult a sports medicine specialist (usually an orthopedic physician).

More Info


Ankylosing spondylitis (AS) is a chronic inflammatory disease primarily affecting the spine and sacroiliac joints, leading to pain and stiffness. Managing pain effectively is crucial for improving the quality of life for individuals with AS. Your son, at 19 years old, has been diagnosed with AS and has experienced varying degrees of pain, particularly in the lower back and buttocks.
1. Can NSAIDs Alone Relieve Back Pain in Ankylosing Spondylitis?
Nonsteroidal anti-inflammatory drugs (NSAIDs) are often the first line of treatment for managing pain and inflammation associated with AS. They can be effective in reducing pain and improving function for many patients. However, the response to NSAIDs can vary significantly among individuals. While some patients may find substantial relief with NSAIDs alone, others may require additional therapies, especially if their symptoms are more severe or persistent.
In your son's case, it seems that while he has had some relief from his buttock pain with the use of NSAIDs like Celebrex (salsalate), the addition of back pain may indicate a more complex situation. It is not uncommon for patients with AS to experience varying levels of pain that may not respond adequately to NSAIDs alone, particularly if there is significant inflammation or structural changes occurring in the spine.
Therefore, while NSAIDs combined with appropriate exercise can help manage pain for many, it is essential to recognize that some patients may need additional treatments, such as physical therapy, disease-modifying antirheumatic drugs (DMARDs), or biologic therapies, especially if NSAIDs are insufficient.

2. Could the Back Pain Be Due to an Injury?
The possibility of your son's back pain being related to an injury, such as from playing badminton, is worth considering. However, given that the pain has persisted despite reduced activity and does not seem to worsen or improve significantly, it is less likely to be solely due to an acute injury.
In young individuals, it is indeed possible to experience sports-related injuries, but these typically present with more acute symptoms and often improve with rest. The chronic nature of your son's pain, along with the underlying diagnosis of AS, suggests that the pain is more likely related to the disease process rather than a simple sports injury.
The fact that his CRP and ESR levels have fluctuated but remain relatively low indicates that there may not be significant systemic inflammation at the moment, which is a positive sign. However, the persistence of pain suggests that there may still be localized inflammation or other factors at play.

3. Management Recommendations:
- Continued NSAID Use: It is essential to continue using NSAIDs as prescribed, as they can help manage pain and inflammation.

- Physical Therapy: Engaging in a structured physical therapy program can be beneficial. A physical therapist can provide exercises tailored to improve flexibility, strength, and posture, which are crucial for managing AS.

- Regular Exercise: Encourage your son to maintain a regular exercise routine, focusing on low-impact activities such as swimming, cycling, or yoga, which can help alleviate stiffness and improve overall function.

- Follow-Up with Rheumatologist: Regular follow-ups with a rheumatologist are essential to monitor disease progression and adjust treatment plans as necessary. If NSAIDs are not providing adequate relief, discussing the possibility of DMARDs or biologics may be warranted.

In conclusion, while NSAIDs can be effective for managing pain in AS, they may not be sufficient for everyone, especially in cases with more severe symptoms. A comprehensive approach that includes medication, physical therapy, and regular exercise is crucial for managing your son's condition effectively. Always consult with his healthcare provider for personalized recommendations and treatment adjustments.
