A 24-year-old female presents with bilateral ankle oedema, which she reports has developed over the course of the last few months. She is usually fit and well, and she mentions the only time she felt seriously unwell was last year when she was struck down by a sore throat. She recalls visiting the GP on that occasion, who noted the back of her throat looked red but felt the aetiology was viral and, therefore, did not give antibiotics.
