What is Autoimmune urticaria

Schnitzler syndrome is a rare autoinflammatory condition. Signs and symptoms of the condition vary but may include urticaria; recurrent fevers; joint pain and inflammation; organomegaly (abnormally enlarged organs); and/or blood abnormalities. The exact underlying cause of the condition is unknown; however, most cases occur sporadically in people with no family history of the condition. Treatment is focused on alleviating the signs and symptoms associated with the condition and may include various medications and/or phototherapy.[1][2][3]
