Hi Gerg! Welcome to DermaTalk. Basically rapid heating of the body with obstruction of sweat duct probably causing your heat rash. Wearing loose cotton clothings, rapid cooling and maintaining Of body temperature taking cool shower with menthol containing soaps may be helpful. Topical application of calamine lotion with oral antihistamines like fexofenadine may help you calm the itching.In severe cases mild hydrocortisone cream along with some antibiotic ( in case of infection like mupirocin) may be helpful. Powers containing antibiotic may also be used .
Hope you will us updated we will be happy to hear from you.
