Answer: I have had it and it lasted about 4 weeks. However Pityriasis rosea usually goes away within 6 - 12 weeks. The itching was the worst for me the Doctor gave me a benovate 1n 4 solution to calm it down I had it over christmas a few years back. If you have the rashes you should have no futher sysptoms than you already have. Apart from swollen glands and the rash I didnt have any other symptoms. My doctor had never seen it before outside of medical texts and had to show his colleage. It is nothing serious and should pass with out getting any worse. Also once the symptoms have gone you should have life long immunity. Apart from looking rather scary it is a mild skin ailment hope you recover quickly.
