Pityriasis rosea is a skin disease marked by patches of pink, oval rash. Although its exact cause is unknown and its onset is not linked to food, medicines or stress, it is thought that this essentially non-contagious condition is set off by a virus.
- The symptoms of this condition include:
- Pink and flaky oval-shaped rash, not dissimilar 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.
