I have a skin rash, postcard sized, brownish in color, almost leathery looking. it's very itchy and i've had it for months. how do i get rid of it?

See a dermatologist: It is difficult to make a proper diagnosis since I am not there to see the condition. I recommend seeing a dermatologist so that they can make a proper diagnosis and give you something to get rid of the condition or relieve symptoms.

Eczema: A localized patch of eczema that has become thickened form scratching is called lichen simplex chronicus. The treatment is a prescription strength topical corticosteroid.
