It is difficult to diagnose a skin condition without seeing it in person. If you have a red, itchy spot on your ankle that has grown to the size of a quarter and has persisted for three months, it is best to see a dermatologist for an accurate diagnosis and appropriate treatment. Self-treating skin conditions can be dangerous and may delay proper healing. A dermatologist can examine the spot, determine its cause, and recommend the best course of action for treating it.
