Rheumatic pain that moves is usually caused by a patient suffering from wandering rheumatoid arthritis. Wandering rheumatoid arthritis is a condition in which rheumatologic patients experience symptoms of migratory pain during the onset of the disease. Patients may be infected with hemolytic streptococcus bacteria, which causes the body’s immune system to produce an overactive immune response that violates the surrounding joints. Patients infected with hemolytic streptococcus may develop arthritis in relatively large joints, at which point migratory pain develops in and around the joints. In addition, it may also invade the internal organs of the body, leading to rheumatic myocarditis, acute glomerulonephritis and other diseases. Therefore, if the patient has rheumatic pain wandering all over the body, it is recommended to go to the hospital in a timely manner, under the guidance of the doctor for diagnosis and treatment, so as not to delay the condition.
