Can rheumatoid arthritis cause nodules?
Rheumatoid arthritis (RA) is a chronic autoimmune disease that primarily affects the joints. One of the notable features associated with this condition is the formation of rheumatoid nodules. These nodules are firm lumps that typically develop under the skin, usually over areas subjected to pressure, such as the elbows, forearms, and heels.
Rheumatoid nodules are considered a characteristic manifestation of rheumatoid arthritis and can be found in up to 25% of patients with this condition. They are generally painless but can sometimes be associated with joint pain. The presence of nodules often indicates more severe forms of the disease and can be associated with a higher likelihood of joint damage.
While the exact cause of these nodules is not completely understood, it is believed that they are related to an immune response where the body attacks its own tissues. Factors such as the severity of the disease, prolonged inflammation, and smoking may contribute to their formation.
It’s important for individuals with rheumatoid arthritis to monitor any changes in their symptoms and consult with their healthcare provider. Effective management of RA through medications and lifestyle adjustments can reduce the incidence of nodules and improve overall joint health.
