How can you cure or help stop itching of pityriasis? - i had pityriasis

I have a virus called pink skin. I've had for about 2 months. Their distribution and eczema has become more and more each day and makes me to sleep. How can I get rid of it or stop the itching? Ive tried E45 and this cream that people use to dry the skin, but it does not really help.
