#asktheexperts My son sweats a lot and has heat rashes on his face,behind ears,neck and chest mostly where sweats collects. The doctor prescribed Histocalamine, Dermocal plus and Aloegrace moisturiser. I also tried regular calamine lotion but there is no real improvement. The rashes remain or get worse with more sweating. I would like to know is there any other calamine lotion that works ? Or any other cream or lotion for heat rash in children ?
