History and Symptoms

The symptoms of this condition include:

• Pink and flaky oval-shaped rash, similar to ringworm
• A single "herald" patch may occur 1 to 20 days before smaller, more numerous patches of rash. It has also been known for the "herald" patch either not to be noticed or not to exist. Other "herald" patches may appear as a cluster of smaller oval spots rather than a single patch.
• Often occurs in patches arranged in a triangular pattern, like a "Christmas tree"
• 25% of people with Pityriasis Rosea get mild to severe itching. This fades as the rash develops
• May be accompanied by headache, fever, nausea and fatigue
• Other less common symptoms include reduction in sweat gland activity and the clearance of acne

These rashes are often found on the back, chest / stomach, inner thighs, inner upper arms and inner forearms. It has been seen occasionally on the palms of the hands. Usually it does not affect the face; however a few blemishes may be found on the cheeks.
