Joint pain is often dismissed as ageing, overuse or a minor injury. But for some people it is the first sign of inflammatory arthritis, a group of immune-driven conditions that can damage joints and other organs if not treated promptly.

Inflammatory arthritis can take years to diagnose and receive treatment, with some forms taking an average of nine years . During that time, persistent inflammation can lead to irreversible joint damage, fatigue and reduced mobility.
Although there is no cure, advances in medication over the past 15 years mean many people can live full and active lives. Outcomes are best when treatment begins quickly, ideally within the first three months , often described as a critical "window of opportunity".
Inflammatory arthritis is less common than osteoarthritis and is managed in different ways. It occurs when the immune system mistakenly attacks the body's own tissues, particularly the lining of joints. The exact cause is often unclear.
It can begin at any age, including in childhood , and often starts in the hands and feet. Some forms affect just the spine and pelvis. Other parts of the body such as the skin, eyes, heart and lungs may also be involved. Joints can become swollen, warm and tender, and many people experience morning stiffness that lasts for hours and improves with movement rather than rest.
Early symptoms can be subtle and easy to overlook. Stiffness may be blamed on sleep, swelling on overuse and fatigue on stress or ageing. This can contribute to delays in referral and specialist assessment.
How inflammatory arthritis differs from osteoarthritis
Osteoarthritis is different. It is strongly associated with age and most often affects people from midlife onwards, particularly in the knees, hands and hips. It usually develops gradually and becomes more common with advancing age.
Inflammatory arthritis, by contrast, is driven by the immune system and often causes prolonged morning stiffness, visible swelling and fatigue that do not improve with rest or simple activity. Although osteoarthritis is far more common globally, affecting more than 600 million people , over 18 million people live with rheumatoid arthritis, the most widely recognised form of inflammatory disease.
Despite these differences, early-stage arthritis can be difficult for healthcare professionals to distinguish . Symptoms often overlap, and no single test confirms the diagnosis. Blood tests and imaging can support assessment, but results are not always definitive. Because treatment varies depending on the type of arthritis, accurate and timely diagnosis is essential.
Medications for inflammatory arthritis aim to control the immune response and reduce inflammation. These include steroids, which are generally not suitable for long-term use, and disease-modifying anti-rheumatic drugs (DMARDs). When introduced promptly under specialist care, these treatments can reduce symptoms and slow disease progression. Some people reach remission: inflammation is well controlled and symptoms are minimal or absent. A small proportion are even able to stop medication under specialist supervision.
Treatment for osteoarthritis focuses on managing pain and improving function. There are currently no medications that reverse the condition or target its underlying cause. Paracetamol, anti-inflammatory drugs such as ibuprofen, and steroid injections may help relieve symptoms. Non-drug approaches are important for both inflammatory arthritis and osteoarthritis. These include exercise, walking aids where needed, heat and cold therapies and some complementary approaches. Lifestyle also plays a key role. Maintaining a healthy weight, stopping smoking and staying physically active can all improve outcomes.
Why early assessment matters - and who to see first
Reaching specialist care quickly can make a significant difference. In the UK, new roles in primary care are helping people be assessed sooner. First contact physiotherapists (FCPs) working in GP surgeries can recognise early symptoms of inflammatory arthritis and refer patients to rheumatology specialists to begin appropriate treatment. They assess people with joint and muscle problems, request tests where appropriate and provide advice on treatment and long-term outlook. If specialist care is needed, they arrange referral directly.
First contact physiotherapists have been part of UK primary care for more than a decade. Evidence suggests the role is safe, cost effective and beneficial to patients, with patients reporting high satisfaction and doctors expressing confidence in physiotherapists' expertise.
Arthritis is a leading cause of pain, stiffness and disability worldwide. For people with inflammatory forms of the disease, delayed recognition remains one of the biggest barriers to effective treatment . Symptoms can resemble more common joint problems, slowing referral to specialist care at the point when treatment would be most effective.
If you notice persistent joint swelling, warmth or morning stiffness that lasts more than an hour or improves with movement, assessment is important. There are UK-based websites that include symptom checkers to help people understand when to seek advice. Many GP surgeries in the UK offer appointments with first contact physiotherapists, which can usually be requested directly.
Joint pain is common and often harmless. But when symptoms persist, involve visible swelling, or do not behave like typical "wear and tear", they should not be ignored. Prompt assessment and appropriate referral give people the best chance of protecting their joints, preserving mobility and maintaining quality of life.
