What causes Pityriasis Rosea?
The cause of this condition has not been identified. It is thought that viruses can trigger pityriasis rosea in some cases.
What are the symptoms?
Pityriasis rosea begins with large, slightly raised, scaly rash (called a herald patch) on the back, chest, or abdomen. In most cases the rash is preceded by mild cold-like symptoms including headache, fever, and fatigue. The initial rash will be followed by more itchy patches or tiny bumps that spread out in a pattern some describe as looking like a fir tree.
