[|Human|] Hi,I have a recurring itch on my right shin. I was told I had this as a young child and my mother treated it with some sort of cortizon ointment. When it seemed to come back during the last few years the itch would normally be light for a day or two and then get intensified to the point where Ill itch until the skins breaks. I tried using some low strength cortizon cream for a week but could not notice any real effect.The itch tend to come and go. I might be itchy for about 4-5 days and then not itch for a week or two and then come back again.What could it be?
[|AI|]  Hello mitraWelcome to Chat Doctor It seems like you are suffering from chronic eczema what we call lichen simplex chronic us. But a fungal infection (Tina) has to be ruled out by a dermatologist first. If it is lichen simplex a mild steroid like portion may not work. You might require a more potent steroid like clobetasol propionate ointment twice a day. Frequent application of a moisturizing cream will also give added benefit. Avoid touching or scratching the rash as it tends to worsen it. So half the treatment is in your hands. Hope this helpedTake care.
