Excuse me how to get urticaria to do

Urticaria is an allergic skin condition. Patients usually need to go to the hospital for an allergen test. Avoid contact with allergenic substances as much as possible. Take loratadine and other antihistamines as prescribed. Apply calamine lotion to relieve itching if the itching is severe. Hydrocortisone ointment should also be applied to local skin to promote the disappearance of the rash.
