Hello, Itchy rash after a holiday is commonly due skin irritation such as sunburn or rashes from poison ivy or allergy. Spots appear anywhere on the skin, may be scaly or itchy. They often flare up in warm weather & get better in cooler climates.  Wash all your clothes & bedsheets in hot water & salon. Take regular bath, keep your skin clean.  Chat Doctor.
