Hi. I've had an extremely itchy sore rash all over my stomach, bum, thighs, arms, ribs and wrists for the last month or so. I try not to itch but it gets overwhelming and I have sores and the rash is just spreading. I havent changed any wash powder or soap etc..I am incredibly stressed at the minute (losing hair too). .what do you recomend to stop the itch or relieve it a bit?
