7. Rheumatoid Nodules: A Distinctive Feature of RA
Rheumatoid nodules are firm, non-tender lumps that can develop under the skin in individuals with rheumatoid arthritis. These nodules are most commonly found on areas subject to pressure, such as the elbows, fingers, and the back of the heels. They are composed of inflamed tissue and can vary in size, ranging from a pea to a golf ball.
The exact cause of rheumatoid nodules is not well understood, but they are believed to be a result of the immune system’s attack on the body’s tissues. These nodules may come and go over time and are more commonly seen in individuals with severe or long-standing RA.
While rheumatoid nodules are typically painless and do not cause functional impairment, they can be a cause of concern for patients and may be a visible sign of the disease’s progression. In some cases, nodules may become infected or cause discomfort, requiring medical intervention. (7)
