POMPHOLYX

Currently 36 weeks. I've been having very itchy feets and hands. They get super itchy from time to time. I have not changed any products I've been using since the start of pregnancy. No contact with any chemical products either. The itchy just started around 35 weeks. Tiny bumps that turn into blister like if I scratch too much. Has anyone else been through this? Went to polyclinic and doctor said its pompholyx. And prescribed a cream for it. Seems it contains very less percentage of steroid too. However after applying it just seems to have gotten worst.
