Quick answer
What is arthritis?
Arthritis means inflammation or damage affecting joints. Osteoarthritis is linked to joint wear and repair; rheumatoid arthritis is an autoimmune inflammatory disease. Persistent pain, swelling or stiffness deserves assessment because early treatment can protect joints and function.
Common patterns
Osteoarthritis often causes pain and stiffness in knees, hips, hands or spine. Inflammatory arthritis may cause prolonged morning stiffness, swelling and symptoms in several joints.
Assessment
A clinician considers the pattern, duration and examination findings. Blood tests, X-rays or ultrasound may help, depending on the suspected type.
Treatment
Treatment can include tailored exercise, weight management where appropriate, pain relief, physiotherapy and condition-specific medicines. Suspected inflammatory arthritis may need early specialist referral.
Common questions about arthritis
- What is the difference between osteoarthritis and rheumatoid arthritis?
- Osteoarthritis involves changes in cartilage, bone and the whole joint; rheumatoid arthritis is an immune condition causing persistent inflammation.
- Should I rest an arthritic joint?
- Short rest can help a flare, but prolonged inactivity often increases stiffness and weakness. Graded movement and strengthening are usually beneficial.
- Is there a blood test for arthritis?
- Blood tests can support diagnosis of inflammatory arthritis but do not diagnose every type. Examination and sometimes imaging are also used.
