hello X my dearest brother was diagnosed a year ago , he's had light UV llight treatment , he's has 50/50 skin cream and a demol cream , his itching is now unbearable and it's Saturday and wondering if I can get something over the counter to ease till Monday when he can see gp ? His skin has got worse the last week , he has a great dermatologist a professor, he's made his skin bleed and I've given him antihistamine tablets , I'm so worried , Linda x
