Arthritis & Rheumatic Diseases (Joint Pain)
“Arthritis” literally means joint inflammation. Although joint inflammation is a symptom or sign rather than a specific diagnosis, the term ‘Arthritis’ is often used to refer to any disorder that affects the joints. These disorders fall within the broader category of Rheumatic disorders. There are diseases characterised by inflammation of one or more connecting or supporting structures of the body. They especially affect joints, tendons, ligaments, bones, and muscles. Some common signs and symptoms are pain, swelling, and stiffness. Some rheumatic diseases also can involve internal organs. Based on patient history and physical examination, the doctor may order laboratory tests and x-rays or other imaging tests to help confirm a diagnosis. A sample of blood, urine, or synovial fluid (lubricating fluid found in the joint) may be needed for the lab tests.
