Erythema nodosum is an inflammatory skin condition that affects the subcutaneous fat layer. The condition produces red painful bumps that are located most frequently on the front portion of the lower legs. The nodules are approximately 1 to 5 centimeters in diameter. The condition may resolve on its own within 3 to 6 weeks. The skin may appear bruised after the nodules subside. An indentation may be present in the skin if the fatty layer underneath has been sufficiently injured.
