Patient: Description of condition (onset, main symptoms, hospital visited, etc.): itchy skin on the legs, long packets, starting at about 2 mm in size, itchy, slowly getting bigger and becoming a large packet! No blisters. Can disappear quickly. It has been off and on for half a month, and recently it has been on all days of the week, more serious at night and in the morning. I have applied medicine, but the effect is not obvious. This week it seems to be a bit unwell, always in a cold. I was treated at the Guangzhou Military Hospital and the doctor said it was hives. I want to find out the cause of the disease, whether it is caused by tumors, as well as itching of the skin caused by Huang Heng, etc. Reply: The cause of urticaria is allergy, and the cause of allergy is different for everyone. Part of it is due to chronic inflammation in the body, such as otitis media, pharyngitis, etc. Patient: In a case like the one I described, is there any itchy skin due to a disease such as a tumor! Reply: Tumors rarely cause hives, if you are really unsure, you can check the ultrasound liver, gallbladder, spleen, pancreas, kidneys and bladder for about 100 yuan, and then check a tumor five and nasopharyngeal cancer screening for about 200 yuan, excluding the general tumor will be relieved! Jaundice can cause yellowing of the skin and mucous membranes throughout the body, so if you are still unsure, check your liver function. You should still focus on the hives themselves
