[Oliviaclay26]

Hello I have never been on one of theses groups so not sure how it works,but seeing if anyone has some advice for me I gave birth 5 weeks ago and have developed an insanely itchy rash all over my body, to the point it bleeds I have been to the doctors multiple times and they not sure what it is.

I have been prescribed steroid creams but they did not help then I was prescribed antibiotics, but they also didn’t work I have now been prescribed strong antihistamines but they are also not working. I also have to put calimine lotion on every night to help stop the itching but it don’t work. I can’t sleep as I am waking up scratching so much and I can’t even feed my new born without having to stop, to itch I have tried to stop itching but I have had it for over three weeks now constantly please if anyone has any advice I would love to know x
