Psoriasis affecting breastfeeding

Hi there, I’m a mummy to 2 kiddies the youngest is just 3 months. I’ve had a huge psoriasis flare since being pregnant which is getting worse and is now covering my breasts and I am breastfeeding, I am really worried about having to stop nursing if it gets much worse and am desperate for any advice on natural/breastfeeding friendly treatments I can try to keep it at bay whilst I wait to see a dermatologist. Any experiences shared would be hugely appreciated please? Thanks 😀
