Management of lower leg rashes
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.
