Rheumatology
Rheumatology is a field of medicine that focuses on the diagnosis and treatment of diseases that share an inflammatory component in their bones, muscles, joints, and internal organs.
Rheumatic diseases, which include many types of arthritis, lupus, and Sjögren's syndrome, are a group of more than 100 complex diseases that fall under the umbrella of rheumatology. Rheumatologists are medical professionals who have completed formal training in the field of rheumatology.
Rheumatology and immunology, the medical field that studies the immune system, have a lot in common given that many of these illnesses are now understood to be immune system disorders.
