What is pityriasis rosea?

Pityriasis rosea is a self-limiting rash that can appear in both adults and children. Pityriasis rosea is more common in children and young adults. It's most common in people between the ages of 10 and 35. It is more common in the spring and fall months.

Its exact cause is unknown. No germ (bacterium, virus, or fungus) was found in people with a rash. However, certain types of human herpes viruses can be part of the cause. It is not associated with food, medication, or stress. However, some medicines can cause a rash that resembles pityriasis rosea.

Pityriasis is usually not contagious and does not spread to other people.

Living with pityriasis rosea.

Most people with pityriasis rosea are perfectly fine but are aware of a rash. The rash may be itchy, but it isn't always. Some people may have:

  • A mild headache
  • A high temperature (fever).
  • Feeling sick (nausea).
  • The feeling of being more tired than usual.

Any symptoms that occur usually start before the rash appears. Some people develop severe itching before the rash first appears.

Occasionally, some people also have areas in their mouth, such as blisters or ulcers.

What does the rash look like in pityriasis rosea?

A "Herald Patch" usually appears on the skin first. This is usually an oval or round spot that can be 2 to 5 cm in diameter. This color is usually pink / red. It mostly appears on the chest or upper back. It can sometimes appear on your stomach (stomach), neck, back, thighs, or upper arms. However, in many cases there is no Herald patch or it goes unnoticed.

About 5 to 15 days later, a more widespread rash will appear after about 10 days. Most often this is on the back or the chest and stomach. This rash can spread all over the body. However, it usually doesn't affect your face.

The rash usually consists of oval-shaped spots 1 to 3 cm in diameter that are pink in color. These spots are smaller than the Herald patch. Often times, the spots appear to form lines parallel to the folds of the skin.

This rash can be very itchy. The rash will subside over time, but this can take several weeks. It doesn't leave any marks or scars. Second attacks are very rare but have been reported.

This description is the typical case that most people seem to have. Occasionally, the rash can only affect the arms and legs. In rare cases, flaking or flaking of the skin can occur, which can be annoying.

Do i need tests?

Tests are usually not required. Your doctor can diagnose pityriasis rosea based on the typical rash. If the rash does not go away after three months, or the itching is severe, you may be referred to a dermatologist. You can also be referred if your doctor is unsure of the diagnosis.

What is the treatment for pityriasis rosea?

Pityriasis rosea is a condition that will clear up naturally. No treatment is required. It usually lasts 2-12 weeks, but can last up to five months. Most often it takes about five weeks before it goes away completely.

Although this rash goes away without leaving a scar, some people have noticed discoloration on the skin for a few months.

There is no treatment that will clear the rash faster than its natural course. The following can help if itching is a problem:

  • Avoid flavored soaps, hot water, wool, and synthetic fabrics.
  • Try not to scratch as much as you can. It is believed that scratching can worsen the itchiness and create a regular scratch cycle. (That is, you itch more because you scratch, so you scratch more because you itch more ... and so on.)
  • Simple creams (also called emollients) can soothe the skin and reduce itching.
  • A menthol cream or ointment can have a cooling and calming effect.
  • Antihistamine tablets can help reduce itching. These can be prescribed by your doctor or bought from a pharmacy.
  • Your doctor may prescribe a steroid cream if the itching is more severe.
  • If the symptoms are very severe, you may be referred to a dermatologist who will recommend ultraviolet light treatment. There is no clear evidence that this is effective. however, it is often tried.
