5. Associated symptoms: Fever, weight loss, malaise
6. Past history: Joint pains, rheumatic fever, recurrent sore throat.
7. Physical examination: Look for anaemia, pallor, skin rash or pigmentation.
Examination of joints: Soft tissue swelling, wasting of muscles, colour of skin overlying joint, movements of joint – range, deformities.
