Starting treatment with combination disease-modifying antirheumatic drugs (including methotrexate), especially within three months of symptom onset, can slow disease progression and improve symptoms, function, and quality of life
When rheumatoid arthritis is suspected, x ray symptomatic joints and measure rheumatoid factor, erythrocyte sedimentation rate, and C reactive protein without delaying referral, as negative results do not exclude the diagnosis
A 43 year old woman with six weeks of bilateral wrist pain is diagnosed with repetitive strain injury. Five weeks later, she returns with worsening pain. On further questioning, she reports increasing fatigue and two hours of morning stiffness in her hands. Examination reveals bilateral wrist and metacarpophalangeal joint swelling. She is referred to a rheumatologist, who diagnoses rheumatoid arthritis and initiates treatment.
