my mother has had a rash for about a week now and its red spots all over her like a rash. she is also complaining of itching everywhere, but mostly her hands and feet , it has also spread to her genital area. she says nothing helps for the itching and we dont know what could have caused it. she was prescribed prednisone but she has taken it before without any reactions so we dont know what could be causing the itching and rash. she hasnt taken any other new medications . any suggestions? she is about to mentally break down if she doesnt find some sort of solution. thank you, Lyndsey F
