I'm a 41 year old female with sudden onset rash, pyrexia, joint inflamation (with pain, swelling, stiffness and heat), nausea, abdo. pain, chest pain on breathing and coughing, hot and sore swellings to lower legs (not deep-vein), ESR 44, CRP 123, low albumen, border-line anaemia. ANA and rheumatoid factor negative, ferritin normal, strep negative. Any ideas?
