What are rheumatic nodules?

Rheumatic nodules are inflammatory nodules formed by the deposition of immune complexes in the dermis or subcutaneous tissue. The main causes include: 1. Immune abnormalities: The body's immune system mistakenly identifies and attacks self-antigens, forming immune complexes that deposit in the skin tissue and stimulate local inflammatory responses. 2. Genetic factors: Individuals with a family history of the condition have an increased risk of developing rheumatic nodules. 3. Infections: Invasion of pathogens such as bacteria and viruses may induce immune responses that lead to the formation of nodules. 4. Environmental factors: Prolonged exposure to damp and cold environments may impair blood circulation, causing local tissue ischemia and hypoxia, which can lead to aseptic inflammation and further development of nodules. Rheumatic nodules may be accompanied by symptoms such as joint swelling, pain, fever, and fatigue. Treatment options include medication, surgical intervention, and physical therapy. Specific treatment plans should be determined based on individual conditions and medical advice.
