Recurrent rheumatism (iatrogenic rheumatism) is not a rare disease in rheumatology practice. According to foreign research studies, the age of prevalence is around 30 to 40 years old for young adults, and the proportion of men and women is about equal. The cause of this disease is still unclear, but it is related to genetic and environmental factors, and a few patients feel that it is associated with certain foods, climate changes, or after childbirth. The clinical manifestations of relapsing rheumatism have the following characteristics: sudden onset of arthritis or inflammation of the soft tissues surrounding the joints (tendonitis, ligamentitis, bursitis). The joints initially attacked are the knees, fingers and shoulders. Patients often describe the symptoms as “running around”. Most patients have a single attack that affects only one joint, while a few patients may have more than three attacks. The pain is sometimes so severe that it makes it difficult to walk or get out of bed. Even if no medication is taken, it will heal spontaneously. In a few patients, the attacks can last up to two weeks. The frequency of attacks may vary from a few times a year to a few times a month. It is well treated with pain and anti-inflammatory drugs. Tests for rheumatism, immunity, blood and uric acid are normal. Insomnia, stress, overexertion, and climate change can trigger the disease. The clinical signs of relapsing rheumatism are sometimes very similar to those of gout or rheumatoid arthritis, and may be mistaken if not carefully examined. According to well-known foreign rheumatology journals, more than half of the patients with this disease still live peacefully with recurrent rheumatism after years and years, about 15% of the patients will be cured by themselves, and about 5% of the patients will turn into rheumatoid arthritis. Therefore, in general, relapsing rheumatism is a good prognosis for arthritis, although it can bring physical or psychological problems to patients, but do not worry, as long as the arthritis attacks take pain relief and anti-inflammatory drugs, this disease will not cause joint deformation, crippling situation. However, if you find that the frequency of joint pain attacks is increasing, the duration of attacks is getting longer, and the effect of medication is getting worse, you need to follow up with an experienced rheumatologist to see if there is a possibility of turning into other arthritis.
