My 5 y.o. Daughter developed a sudden rash while in the shower. She was using a mild cleanser that she uses all the time & the water wasn t too hot. The rash wasn t itchy, she said it didn t really hurt, and is fading now. It looked somewhat like a splotchy sunburn all over the front of her trunk, neck, & legs.
Hi, As per your query, your child has symptoms of rash on neck and legs which is mainly due to contact dermatitis. Need not worry. I would suggest you keep this area clean and Chat Doctor.  Apply warm compresses with a soaked towel and apply vitamin C serum at night. If the condition doesn't get better than consult a dermatologist for proper examination. The doctor will examine physically and may prescribe immunosuppressants. Avoid itching and pricking rashes. Hope I have answered your query. Let me know if I can assist you further.
