Joint pain and swelling are common symptoms that can affect people of all ages. While they may result from injuries, overuse or other temporary causes, persistent or recurrent symptoms may indicate inflammatory arthritis, autoimmune diseases or other underlying conditions requiring specialist assessment. Identifying the underlying cause is important, as different conditions require different treatments. Early diagnosis and appropriate management can help control inflammation, relieve symptoms, maintain joint function and reduce the risk of permanent joint damage.
At the Centre for Rheumatology & Arthritis, Dr Poh evaluates whether a rheumatic or autoimmune condition may be contributing to your symptoms and develops a personalised treatment plan based on your diagnosis.
Joint pain and swelling can result from a wide range of conditions affecting the joints, immune system or surrounding tissues. While some causes may be temporary and improve with appropriate treatment, others may require long-term management to control inflammation, relieve symptoms and help prevent joint damage.
This occurs when the immune system mistakenly attacks the joints, leading to persistent inflammation. Common examples include rheumatoid arthritis, psoriatic arthritis, ankylosing spondylitis and lupus.
Osteoarthritis develops when the protective cartilage within a joint gradually wears down over time. It commonly affects weight-bearing joints such as the knees and hips, as well as the hands leading to pain, stiffness and reduced joint function.
Crystal arthritis occurs when crystals build up within a joint, triggering sudden and often intense inflammation. Gout is the most common form and typically causes severe pain, redness, warmth and swelling.
Bacterial or viral infections can sometimes cause inflammation in or around the joints. When an infection directly affects a joint, it can cause septic arthritis, a serious condition that requires urgent medical assessment and treatment to prevent joint damage and other complications.
Joint pain and swelling may also result from injuries, repetitive strain or overuse of a joint.
The onset, pattern, duration and associated symptoms of joint pain and swelling can provide important clues about the underlying cause. Some conditions develop suddenly and cause severe symptoms, while others develop gradually over time.


You may benefit from a rheumatology assessment if you experience any of the following:

These symptoms do not necessarily mean you have inflammatory arthritis or an autoimmune condition. However, if your joint symptoms are persistent, recurrent or affecting your daily life, a rheumatology assessment can help determine the underlying cause.
Your rheumatologist will assess the pattern and characteristics of your joint symptoms, examine your joints and recommend appropriate investigations to help determine the underlying cause. A comprehensive assessment supports an accurate diagnosis and helps guide a personalised treatment plan tailored to your condition and needs.
Your rheumatologist will discuss your symptoms in detail, including which joints are affected, whether your symptoms are persistent or recurrent, and how they affect your daily activities.
Your rheumatologist will examine the affected joints for swelling, tenderness and warmth.
Blood tests help detect markers of inflammation, uric acid levels and antibodies associated with autoimmune conditions. These results may help support the diagnosis but are always interpreted alongside clinical symptoms and physical examination findings.
Ultrasound, X-rays or MRI may be recommended to assess joint inflammation, cartilage and bone changes or other structural damage. In selected cases, joint aspiration may be performed to analyse joint fluid for signs of infection or uric acid crystal.
Treatment depends on the underlying cause and aims to relieve symptoms, control inflammation, preserve joint function and reduce the risk of long-term joint damage.
Depending on the diagnosis, treatment may include:
Non-Steroidal Anti-Inflammatory Drugs (NSAIDs) NSAIDs help reduce pain and inflammation, especially during periods of acute flares.
Corticosteroids Corticosteroids act quickly to reduce inflammation and relieve pain. They are often used to manage acute flares or to provide symptom relief while other long-term medications take effect.
Disease-Modifying Anti-Rheumatic Drugs (DMARDs): DMARDs help control the abnormal immune response that drives the inflammation in autoimmune diseases. They help slow disease progression, control inflammation and reduce the risk of long-term joint damage.
Biologic and Targeted Therapies: These treatments target specific pathways involved in the immune response to provide more effective control of inflammation.
Urate Lowering Therapies: Urate lowering therapies are long-term medications that reduce uric acid levels in the blood, dissolve urate crystals in the joints and help prevent gout flares.
A tailored physiotherapy and exercise programme can help maintain joint mobility, strengthen the muscles supporting the affected joint and improve strength and overall function.
For autoimmune and inflammatory conditions, regular follow-up helps monitor disease activity and response to treatment, with the aim of maintaining disease control, minimising flare-ups and reducing the risk of progressive joint damage.
Dr Poh Yih Jia is a senior consultant rheumatologist with more than 20 years of medical experience in
New Zealand and Singapore. She has extensive experience in the diagnosis and management of rheumatic,
autoimmune and inflammatory conditions that cause joint pain and swelling, including inflammatory
arthritis, connective tissue diseases and crystal arthritis.
Her commitment to patient-centred care has earned her multiple accolades, including the Singapore Health
Quality Service Award and the Service with a Heart Award. She remains dedicated to advancing
rheumatology through clinical practice, education and research, ensuring her patients receive the most
current, evidence-based care for inflammatory and autoimmune conditions affecting the joints.

Joint pain and swelling can have many causes, including injury or overuse, infections, crystal arthritis such as gout, osteoarthritis and autoimmune conditions such as rheumatoid arthritis or lupus. A medical assessment can help determine the cause and guide appropriate treatment.
Consider seeing a rheumatologist if your joint pain or swelling persists, recurs, or affects multiple joints. A rheumatology assessment may also be appropriate if you experience prolonged morning stiffness or other symptoms such as fatigue, fever, skin rashes or dry eyes and dry mouth.
Diagnosing the cause of joint pain and swelling usually involves a combination of your medical history, physical examination, blood tests and imaging such as X-rays, ultrasound or MRI. In some cases, joint aspiration may be performed to analyse the fluid for signs of infection, inflammation or crystals. Together, these assessments can help identify the underlying cause of joint pain and swelling, including conditions such as gout, osteoarthritis, joint infections or autoimmune conditions.
Yes. Many causes of joint pain and swelling can be effectively managed without surgery. Treatment depends on the underlying cause and may include medications, physiotherapy and lifestyle modifications. Surgery is generally considered when there is significant joint damage or another structural problem that does not respond adequately to non-surgical treatment.
Early diagnosis and appropriate treatment for autoimmune diseases can help control inflammation, relieve symptoms and reduce the risk of irreversible joint damage. Seeking medical assessment early is particularly important when symptoms are persistent, recurrent or worsening.
