Getting a rash after delivery could indeed be Pruritic Urticarial Papules and Plaques of Pregnancy (PUPP). However a diagnosis still needs to be made based on a careful examination of the skin by a medical professional.
As you rightly pointed out, there is also a possibility of scabies. Unfortunately there is not enough information to make a definitive diagnosis.
In the meantime, there are a few steps you can take to help.
- Take antihistamines to relieve the itch.
- Use moisturiser to repair the skin and make it stronger and less prone to breaking, which further aggravates itch.
- Avoid taking hot baths or showers. Whilst doing this might help with the itch initially, the increased blood flow to the skin will make the rash worse afterwards.
- Try putting a wet towel in the fridge. When it itches, place the cold wet towel on the rash to relieve the rash.
Your doctor may prescribe steroid cream or one combined with an antibiotic to reduce the rash.
