Oh someone help me out please!! I'm being driven mad by prickly heat rash right across my chest since about Monday. I've tried everything. I've bought medicated soap. Used the Snake brand prickly heat cooling powder. I've used the anti itch E45 lotion, Antihistamine cream, Hydrocortisone cream and even a antihistamine tablet. Its getting no better and I have a 'do' to go to tomorrow and of course I want to wear a dress that shows the lot! Its currently bright red, scaly and itchy and feels like really bad sunburn. I've had it covered with t shirts etc all over this heatwave so its only a sweat heat rash not a sunburn rash. It feels so rough and dry but if I try to moisturise it it seems to make it worse! I'll be going to this party in a polo neck at this rate!
