Management depends on making a correct diagnosis. General advice should include:
- Avoid and treat dry skin, using non-soap cleansers and thick simple emollients. Avoid exposing the legs to direct heat or the hot air of the heater in a car.
- Minimise swelling ??avoid standing for prolonged periods, take regular walks, elevate the feet when sitting or overnight and wear special graduated compression stockings long term.
- Prescription treatments may include oral antibiotics for secondary infection and topical steroids of varying potency ??weak products can be used long term if necessary but potent topical steroids should be used once or twice daily for short courses of one to four weeks.
