Urticaria is different from pruritus, which is mainly a metabolic disease, while pruritus has no obvious cause, and causes primary itching of the skin. In pruritus, dry skin is an important cause of itching, and in addition, eating foods that are hot and moist, such as barbecue, can aggravate the itching. There are usually scratch marks, blood crusts, hyperpigmentation and tinea-like changes, which will remain for a long time if left untreated. You can apply lotion and moisturizer on a daily basis, which will have some effect on the itch, or you can flush some Pancreatic. Urticaria, also known as cryptorchid, is caused by food allergies, specifically foods high in protein such as milk, eggs, seafood, or allergies to the outside environment, such as dust mites and pollen, paint, etc. Sometimes cold and hot stimuli from the environment around the medication, exercise, or even emotional stimuli can trigger hives. If you have been exposed to any of these triggers and develop a rash, the skin will grow rapidly in size and eliminate quickly, without symptoms if you are not exposed to the allergenic substance. Patients do not have a fixed initiation site, and the skin does not leave any visible traces after the rash recedes and returns to normal. The cluster may protrude from the skin and have a slight erythema. If you have urticaria or pruritus, you should pay attention to your daily diet, eat less spicy and irritating food, and if you prohibit smoking and alcohol, it will help a lot to improve the symptoms, and if you are seriously unwell, you should go to the hospital.
