Itchy neck and red bumps may be clinically caused by allergic inflammation, especially atopic dermatitis or papular urticaria, which are mostly due to allergic factors or exposure to allergens, resulting in local skin metaplasia. Therefore, at this time, local anti-allergy drugs or hormonal drugs can be used to relieve itching and anti-inflammatory, such as topical hydrocortisone butyrate cream or trimethoprim cream, etc., and oral anti-itch drugs can also be taken, such as oral paracetamol or levocetirizine hydrochloride, etc. If the red bumps are not caused by allergies, such as due to infections, especially the fungal infection Malassezia folliculitis, you need to apply antifungal medications, such as topical ketoconazole cream, etc. If these red bumps are caused by viral infections, such as herpes zoster or herpes simplex due to herpes virus infection, prompt antiviral treatment is needed, such as topical acyclovir cream and then oral acyclovir tablets.
