What is Pityriasis Rosea?
Pityriasis Rosea is the self-limiting rash, In other words, it can go away on its own without any treatment. Although the rash can be quite dramatic and irritating, the illness is very mild and often not dangerous. It most commonly affects young adults but can affect people of all ages.Pityriasis rosea is a self-limiting rash that can occur both in adults and in children, better to say in people of all ages. Pityriasis rosea is more common in children and young adults than in older people. It is most common in the age range between 10 and 35 years. It is more common in the spring and autumn than in winter or summer.
Its exact cause is still unknown. No germ (bacterium, virus, or fungus) found in people with the rash which is strange. However, certain types of human herpes viruses may be a reason why people are getting the rash. Is not associated with food, dirty water, medicines or stress. However, some medicines can cause a rash which can look similar to pityriasis rosea
Pityriasis rosea causes a rash. The rash often begins with a single, round or oval, pink patch that is scaly with a raised border (herald patch). The size of the patch ranges from 2 cm (0.8 in.) to 10 cm (3.9 in.). The larger patches are common. See a picture of a herald patch. Days to weeks later, salmon-colored, 1 cm (0.4 in.) to 2 cm (0.8 in.)oval patches appear in batches on the abdomen, chest, back, arms, and legs. Patches sometimes spread to the neck but rarely to the face.Patches on the back are often vertical and angled to form a “Christmas tree” or “fir tree” appearance.Mild itching is a problem for about half of the people who get the rash. The rash usually lasts 6 to 8 weeks, but it can last up to several months. So you have to be aware that rash will stay on you for a relatively long period.
In rare cases, the rash may take other forms. Rounded bumps (papular rash) seen in young children, pregnant women, and people who have dark skin. Blisters (vesicular rash) seen in infants and young children. In some people, the herald patch may not appear, or two herald patches may appear close together.Before the herald patch appears, you may feel tired and as though you have a cold. You may have a headache, nausea, sore throat, and loss of appetite. You should then see the doctor for pensionary reasons.
