A rheumatologist is a medical doctor who specializes in diagnosing and treating diseases that affect the joints, muscles, and bones. They often manage conditions such as arthritis, lupus, and gout, which can cause pain, swelling, and stiffness. Rheumatologists use various tests, including blood tests and imaging studies, to understand a patient's condition better. These specialists work closely with patients to develop treatment plans that may include medications, physical therapy, and lifestyle changes. Their goal is to reduce symptoms, improve function, and enhance the quality of life for individuals with chronic rheumatic diseases.
