We're going to a hot sunny place on hol for 2 wks in Aug - which is lovely but...I suffer terribly from prickly heat and silly though it sounds it's actually making me dread going. Last yr we were away a wk and for over half that time I was so uncomfortable I couldn't relax, had trouble sleeping - and the antihistamines the GP suggested (Piriton) were totally ineffective. Does anyone know of anything that actually works?
