I had PURPP which is hellishly itchy - I used hydrocortisone religiously (don't know if that impacts on liver function) and has to be prescribed by a doc if you're pregnant. I also used Avenno moisturiser - they have one that's loaded with oats and made a huge difference. What a bugger they won't do a CS earlier (yes, I know why it's better for baby) but when you're that itchy and the only thing that will fix it is to get the baby out, I can completely understand why you were in tears
