A.K.
I got PUPPS really bad with my first, and then got it AGAIN with my second. I was so mad, because I'd also read online that it doesn't often affect subsequent pregnancies. Ah! The first time around, my nurse midwife didn't believe it was PUPPS, and let me know another week while it spread EVERYWHERE!! A week later, when I was practically crying in her office, and had tried every cream under the sun, she had a doctor prescribe an oral steroid, which totally took care of the problem. The second time around, I knew exactly what it was, and went in to a new nurse midwife right away. She prescribed a topical (cream) steroid mixed with Sarna cream. This was FABULOUS!!! The cream feels great when you put it on, and it eliminated the PUPPS within several days. Yay! It sounds like your oil is very similar, so maybe if you used Sarna cream in between applications of the oil, you would get that same soothing effect. Keep it up with the oil, the steroids should eliminate the PUPPS. One question, did your doc prescribe a new oil, or are you using the one from last pregnancy? The old one might be expired, and therefore not as effective. Also, PUPPS can be everywhere on your body, although it generally spares the face. Ah!!!
I feel for you honey! Another thing that helps when the Sarna has worn off and you don't get to apply the oil for several hours is ice packs. Wrap an ice pack in a towel and put it on the worst parts of the rash (mine was worst right on my giant belly). Other than that, just hang in there!!!
