Hi,
I went to the doctors last week as ive had really bad itching and a rash all over. He gave me a prescription for oilatum to put in the bath, aqueous cream with menthol and another stronger cream. But to be honest the oilatum and aqueous cream (kept in the fridge) has been the most help, and you can get both of those over the counter at a chemist.
HTH
