I can definitely empathize with how uncomfortable PUPPP can be. It's true that this rash often appears in the third trimester, usually starting on the abdomen and possibly spreading to other areas. While it's more common in first-time pregnancies, it can happen to any pregnant person.
For managing the itchiness, many people find relief with topical corticosteroids and antihistamines, but it's always best to talk with your healthcare provider before starting any treatment. Cool baths or using oatmeal-based creams can also soothe the irritation.
In most cases, the rash resolves after delivery, but it can persist until your baby is born. Keeping the skin moisturized and avoiding hot showers can also help reduce discomfort. If you're still feeling unsure or struggling with the symptoms, reaching out to a dermatologist could provide more tailored solutions.
