There is no internal rheumatism in the current medical diseases, and the internal rheumatism asked by the patient should refer to rheumatoid. Rheumatoid arthritis is a common acute or chronic connective tissue disease with arthritis as the main manifestation, early joints can appear red, swollen, hot, painful and dysfunctional, late joints can appear varying degrees of stiffness, deformity, and muscle atrophy around the joint. The prognosis of the disease may vary depending on the disease, its course and whether the treatment is appropriate: generally, patients with a short onset (within 2 years for patients with mild symptoms and within 1 year for patients with severe symptoms), mild disease, slow progression of the disease, single or few affected joints, no or few complications, and patients who can be diagnosed early, given reasonable therapeutic treatment, and who can adhere to the treatment. It is usually possible to control the progression of the disease and less joint dysfunction occurs. Patients who have had the disease for more than 2 years, have more joints involved, have recurrent episodes of joint swelling, and cannot adhere to treatment have a poorer prognosis. Although most patients with rheumatoid arthritis can temporarily relieve symptoms and control the disease through treatment, failure to adhere to treatment can lead to recurrent disease, leaving some joint dysfunction and worsening with the prolongation of the disease. The prognosis for patients with severe morning stiffness, persistently high rheumatoid factor titers, significantly increased blood sedimentation and C-reactive protein, rheumatoid nodules, severe extra-articular manifestations, and significant systemic symptoms such as fever and anemia is often poor. Therefore, the prognosis of rheumatoid arthritis may vary depending on the condition, the course of the disease and whether the treatment is appropriate.
