#asktheexpert skin rash due to sweating only covering neck area. please guide

A. Prickly heat rash, or miliaria, often affects children when sweat gets trapped under the skin, causing red, itchy bumps. To treat it, keep the area cool and dry, dress in loose, breathable fabrics, and stay in a cool environment. Calamine lotion can relieve itching, and a pediatrician might suggest an antihistamine in severe cases. Prevention involves avoiding overheating, keeping skin dry, and staying hydrated.
