Skin rashes are no fun. They're itchy, irritating, and can be embarrassing. They can appear out of the blue, and you haven't the slightest clue what caused it. One such rash is known as pityriasis rosea. It occurs mostly in the Spring and Fall, so many people may be noticing it on their bodies now. This rash usually lasts for only couple of weeks, but for the unlucky few, it can last as long as three months. You'll usually see one large patch known as the herald or mother patch on the chest or back. Then within a week, smaller pink patches begin to appear on the arms, belly, legs, and neck. The patches are oval shaped, and have a distinct border.
This rash is believed to be caused by some kind of virus, but isn't contagious (phew). If you go to the doctor or dermatologist, she can diagnosis pityriasis rosea just by looking at your rash, but she may take a skin biopsy just to be sure.

Gentle bathing, taking antihistamines, and applying a topical hydrocortisone cream can help deal with the itchiness, but they won't make the rash go away. I would never support UV sun exposure, but apparently moderate time in the sun or indoor tanning can make the lesions disappear more quickly. Though DrSugar warns that while sun exposure can be helpful, watch out for sunburns: they can make the situation worse and most cases will resolve spontaneously without treatment.
The good news is that once you get pityriasis rosea, recurrence is unusual.
