Pruritic folliculitis begins as lesions on the torso and may spread to other parts of the body.
The lesions contain pus, so they may resemble acne.
It can spread within a few days to weeks as the bumps turn to blisters or large raised plaques. Your doctor may prescribe topical or oral corticosteroids to treat herpes gestationis.
Others may be a symptom of an underlying condition that requires medical attention to keep you and baby safe.
Usually, the rash is due to irritation caused by the diaper and moisture, but it can have other causes not related to diapers.
Irritant rashes are most common and are caused by skin contact with pee, poop, and sweat.
Treatment for prurigo of pregnancy involves topical steroids and oral antihistamines. While the rash should go away soon after delivery, some people may continue to have symptoms.
The condition may also show up in future pregnancies.
