Hello, I have been taking a course of Clindamycin and have come up in a severe rash which is covering most of my stomach, back, arms and tops of my legs. I have stopped the Clindamycin and have taken antihistamine and also used anthisan cream, but the rash seems to be getting worse and the itching is driving me mad. Is there anything else I can do as I go on holiday on Saturday and getting a doctors appointment is very difficult? Thank you, Gillian
