It is more likely to be eczema, an allergic skin disease with erythema, papules and pimples with obvious itching symptoms as clinical manifestations. Patients with this disease should avoid eating spicy and irritating foods, and should be less exposed to water and should not bathe too often. The treatment can be topical with some hormonal creams, such as Denide cream or hydrocortisone butyrate cream, and if necessary, oral antihistamines, such as loratadine tablets or levocetirizine hydrochloride tablets, but the specific diagnosis and treatment should be carried out under the guidance of a clinician.
