I am having a bad week it started by me falling down the stairs and bruising all my back so I can't lie or sit comfortably and now I seem to have a heat rash all over my face which is really itchy nothing seems to be helping I try to avoid antihistamines as they send me to sleep but cool cloths and e45 cream only work for a few mins has anyone else had this and what did you find helped. I'm fairly sure it's prickly heat and nothing more serious it's only on my face an a bit of my neck
