Hello, doctor. Please help me see what causes my symptoms. Thank you. "Male, 24 years old, Changzhou, Jiangsu Province. My back waist is prone to itching and swelling when the temperature is low. For example, in late autumn, winter or spring, and every time after dinner, after about 6:00 p.m., I itch for an hour and a half or an hour. The more I scratch, the more I itch. When the symptoms appear, the degree of itching is not particularly severe, but I always want to scratch twice. If I can resist it, it's about half an hour." If I catch it, the symptoms will continue. The symptoms of redness and swelling only occur when the scratch is serious. The symptoms do not occur every day. If I go out for a walk or do other things after dinner, it will be all right. Maybe the symptoms appear but I don't feel them. About 3-4 years "
