What are the symptoms of pityriasis rosea?

The main symptom of pityriasis rosea is an itchy rash. Before even noticing the rash, however, people may have symptoms of a cold -- fever, aching head and joints, etc. When the rash does appear, it usually starts with a "herald patch" -- a small, round rash on the abdomen, chest or back. Within the next week or two, smaller spots of this rash will appear on the rest of the body, appearing to spread from the herald patch.

Symptoms of pityriasis rosea begin as one pink or red scaly patch that may itch. After a week or two, other patches begin to appear. They are often oval in shape and are sometimes said to follow a Christmas tree pattern. Pityriasis rosea is a common skin rash that often strikes young adults. Many people do not need treatment, but if the rash is very itchy, you may want to ask your dermatologist for some relief. It's always a good idea to see a doctor or dermatologist about any rash you develop.
