Prickly heat on the neck can be treated by general treatment and medication. 1. General treatment: If the symptoms of prickly heat on the neck are not too obvious, the first thing you need to do is to stay away from hot and humid environments, wash your neck with lukewarm water every day, use prickly heat powder to inhibit the regeneration of prickly heat, and keep the skin on the neck clean and dry, which will usually be cured after a few days. 2. Medication: If the symptoms are more serious and the number of prickly heat on the neck is large, after scrubbing with warm water, you can apply glycerite lotion, zinc oxide ointment and other medications, which can effectively play the role of astringent and itch-relieving, so that prickly heat will subside. However, if secondary infection is caused by scratching, neck friction, improper care, etc., erythromycin ointment, mupirocin ointment and other drugs can be rubbed topically to prevent infection. When prickly heat on the neck occurs, you should go to the hospital immediately, and the medication should be used under the guidance of a doctor.
