Hi my partner has a red, extremely itchy rash that is mainly on the sides of his stomach, arms and feet, but has spread up his neck on his back, fore head and legs. He's had it for over a year, tried everything, been to see 5 doctors, 1 dermatologist and they think its contact dermatitis but no one really has an answer. It's driving me and him insane as he can't sleep and all he does it scratches. He's tried anything from antihistamines, steroid creams, special soaps, bathes everything! Please help. He is 25, about 80kg, 185cm in height, is a concretor but has been for years.
