Pityriasis rosea is a rash that usually begins as a large circular or oval patch on the chest, abdomen, or back and can affect any age group. It is most common between the ages of 10 and 35 and usually resolves without treatment within 10 weeks.
According to what is mentioned by the site mayoclinic The exact cause of pityriasis rosea is unclear and some evidence suggests that the rash may be caused by a viral infection, particularly certain strains of the herpes virus. But it has nothing to do with the herpes virus that causes cold sores. Pityriasis rosea is not believed to be contagious.
Complications of pityriasis rosea are not likely. If symptoms do occur, they can include:
1 severe itching.
2 c The presence of permanent brown spots on dark skin after the rash has healed.
Pityriasis rosea usually begins with the appearance of a scaly, large, slightly raised spot called a spot on the back, chest, or abdomen. Before the precursor point appears, some people experience a headache, fatigue, fever, or sore throat..
After a few days or weeks of starting the precursor spot, you may notice small scaly spots on your back or abdomen that resemble the pine pattern. The rash can itch, sometimes severe..
In most cases, pityriasis rosea will heal on its own within four to 10 weeks. If the rash doesn’t go away within this time, or the itch is bothersome, talk to your doctor about treatments that can help. The condition resolves without scarring and does not usually recur. If home remedies do not relieve symptoms or shorten the duration of rosacea, your doctor may prescribe you a drug. Examples include “corticosteroids, antihistamines and antiviral drugs”.
