Has anyone experience PUPP rash during 3rd trimester? Are there any remedies?

Hi i’m so sorry to hear that 😭i’m currently week 32. Suddenly had eczema flare up last week on my neck and arms. Went to GP and the doc gave me steroid cream and antihistamine (cetrizine) . However i only applied for 1 day as steroid cream does cause hypopigmentation when applied too much/frequently. Went to buy derma lab (specially for eczema) body wash and itch relief cream which are really effective in relieving itch. I told gynae about my situation during my Monday’s visit and he also just told me to take antihistamine and avoid any food i’m allergic to. Hope this helps!
