Rheumatology is the medical specialty focused on diseases that affect joints, muscles, bones, and the immune system. Many people think of arthritis only as “wear and tear,” but the reality is far more complex. Rheumatology treats over a hundred conditions, including rheumatoid arthritis, lupus, psoriatic arthritis, gout, ankylosing spondylitis, and many others. These conditions don’t just affect movement—they impact energy levels, mental health, heart health, and quality of life.
