The application of compression is a mainstay in the treatment of acute and chronic oedema and lymphoedema (Moffatt et al, 2012; Scheer, 2017), as well as in some of their associated comorbidities, such as ulcers (Dumville et al, 2015). We do not always make a clear diagnosis prior to starting treatment and, therefore, do not always get the outcome we expect or achieve an optimal result for the patient. Consideration of differential diagnoses, our diagnostic skills and the time required to make a clear diagnosis are common issues in practice.
