It is possible that hives may appear on the body, mostly due to allergic factors, especially after eating some allergic food or breathing in certain allergic particles, so that hives are produced. It is necessary to avoid clear allergens and then take oral anti-allergy medications, such as antihistamines, levocetirizine hydrochloride, or paracetamol, ketotifen, etc. For localized lesions, you can apply topical anti-itch creams, such as compound camphor cream, or topical glyburide lotion, etc. In some cases, the bumps may be papular urticaria caused by mosquito bites, so hormonal creams such as hydrocortisone butyrate cream or dexamethasone cream can be applied topically.
