Itching of the neck can be caused by allergies or due to non-allergic factors. Allergies are mainly due to eczema, atopic dermatitis, and contact dermatitis, where localized allergic reactions occur in the skin after exposure to allergic substances. In clinical treatment, epidermolysis bullosa capsules or fexofenadine hydrochloride tablets can be taken orally, and topical application of dexedrine ointment or dexamethasone acetate ointment can be applied. For non-allergic factors, which may be due to erythematous scaling diseases such as pityriasis rosea, psoriasis, paronychia, lichen planus, all due to immune disorders, secondary to pruritus in the neck, can be applied topically with Denide ointment.
