<unk>  is self-limiting and usually resolves itself within 3–6 weeks. A recurring form does exist, and in children, it is attributed to repeated infections with streptococcus. Treatment should focus on the underlying cause. Symptoms can be treated with bed rest, leg elevation, compressive bandages, wet dressings, and nonsteroidal anti-inflammatory agents (NSAIDs). NSAIDs are usually more effective at the onset of<unk>  versus with chronic disease. Potassium iodide can be used for persistent lesions whose cause remains unknown. Corticosteroids and colchicine can be used in severe refractory cases. Thalidomide has been used successfully in the treatment of<unk>  leprosum, and it was approved by the U.S. FDA for this use in July 1998. According to a 2009 meta-analysis, there is some evidence of benefit for both thalidomide and clofazimine in the treatment of<unk>  leprosum.
