Key points

  • Ankylosing spondylitis (AS) is a long-term inflammatory condition primarily affecting the spine and sacroiliac joints.
  • The hallmark symptom is persistent back pain and stiffness that improves with exercise but worsens with rest.
  • Management focuses on reducing inflammation through NSAIDs, physiotherapy, and specialist biologic medications.
  • NICE guidelines recommend early referral to rheumatology for anyone with suspected inflammatory back pain.
  • Online GP services can assist with monitoring symptoms, providing sick notes, and managing repeat prescriptions.
  • Regular exercise and posture management are essential lifestyle components for maintaining spinal mobility.

What is Ankylosing Spondylitis?

Ankylosing spondylitis (AS) is a type of chronic inflammatory arthritis that primarily affects the spine and the sacroiliac joints (where the base of the spine meets the pelvis). It is part of a broader group of conditions known as axial spondyloarthritis (axSpA). Over time, the chronic inflammation can lead to the formation of new bone, causing sections of the vertebrae to fuse together. This fusion makes the spine less flexible and can result in a hunched-forward posture.

In the UK, it is estimated that approximately 1 in 200 adults live with AS. While symptoms often begin in late adolescence or early adulthood, a diagnosis is frequently delayed because the symptoms can be mistaken for more common 'mechanical' back pain. However, unlike mechanical strain, AS is an autoimmune-driven condition where the body’s immune system mistakenly attacks its own healthy tissues.

Identifying the Symptoms: Inflammatory vs. Mechanical Back Pain

Common Symptoms of AS

The primary symptom of AS is chronic back pain, but it has specific characteristics that distinguish it from standard back injuries. According to NHS guidance, you should consider the possibility of AS if your back pain:

  • Started before the age of 40.
  • Developed gradually over several weeks or months.
  • Is worst in the early morning or during the night, often waking you up.
  • Is accompanied by stiffness that lasts for more than 30 minutes after waking up.
  • Improves significantly with movement and exercise, but feels worse after periods of rest.

Other Physical Effects

While the spine is the main focus, AS is a systemic condition. Patients may experience peripheral arthritis (pain and swelling in the knees or ankles), enthesitis (inflammation where tendons meet bone, such as the Achilles tendon), and fatigue. In some cases, patients develop uveitis, a painful inflammatory eye condition that requires urgent medical attention.

NICE-Aligned Treatment and Management

Treatment for AS in the UK follows pathways set by the National Institute for Health and Care Excellence (NICE). Because there is currently no cure, the goal of treatment is to alleviate symptoms and slow the progression of spinal fusion.

First-Line Medication

NSAIDs (Non-Steroidal Anti-Inflammatory Drugs) such as naproxen, ibuprofen, or etoricoxib are typically the first treatments prescribed. These help manage both pain and the underlying inflammation. NICE recommends that if one NSAID does not work after two to four weeks, a second variety should be trialled.

Biologic Therapies

For patients who do not respond to traditional painkillers, UK rheumatologists may prescribe biologic medications, such as TNF inhibitors (e.g., adalimumab or etanercept). these are administered via injection and work by blocking the specific proteins that drive inflammation. These are high-level specialist drugs that require regular monitoring for side effects and infection risks.

Physiotherapy and Exercise

Physiotherapy is regarded as equally important to medication. Specific exercises designed to maintain spinal extension and lung capacity are vital. Many UK patients are referred to the National Axial Spondyloarthritis Society (NASS) for community support and specialized hydrotherapy sessions.

How an Online Doctor Can Help with AS

Managing a chronic condition like AS requires consistent medical oversight. While your initial diagnosis and biologic prescriptions will always occur via an NHS or private rheumatologist, a UK online doctor can provide essential support in between specialist appointments.

When you speak to a GP online, you can discuss flare-ups of pain, adjustments to your primary care medications, or concerns about side effects from your daily treatments. Online GPs are particularly helpful for:

  • Symptom Monitoring: Assessing if your current pain management is sufficient or if a rereferral to a specialist is needed.
  • Mental Health Support: Living with chronic pain can lead to anxiety or low mood; an online doctor can provide advice and treatment for your mental wellbeing.
  • Sick Notes: If a flare-up makes it impossible to work, an online doctor can issue a fit note (sick note) following a consultation.
  • Referrals: If you have new symptoms suggesting AS, an online GP can review your history and provide a private referral to a specialist for blood tests (like the HLA-B27 marker) and MRI scans.

Lifestyle Adjustments for Better Mobility

Beyond medical intervention, lifestyle changes can significantly improve the quality of life for those with AS. Maintaining a healthy weight reduces the load on the spine and joints. Quitting smoking is also crucial; research shows that smokers with AS tend to have more aggressive spinal fusion and poorer responses to treatment compared to non-smokers.

Posture management is another key area. Using a firm mattress and avoiding thick pillows can help prevent the neck from fusing in a forward-leaning position. At work, ensure your desk is set up ergonomically, and take frequent 'movement breaks' to prevent the stiffness that sets in during prolonged sitting.

Red flags — when to seek urgent help

Call 999 or go to A&E if you experience any of the following:

  • Sudden, painful, red eye with light sensitivity (possible uveitis).
  • New or worsening numbness in the 'saddle area' between the legs.
  • Sudden loss of bladder or bowel control (potential cauda equina syndrome).
  • A sudden, severe fracture-like pain in the back following a minor fall.
  • Difficulty breathing or chest pain caused by extreme ribcage stiffness.
