Post-partum rashes

Hi mummies anyone experiencing the same? I started getting afew rashes 5 days post-pregnancy. Initially was just at my tight area now feels like whole body - hands, legs, buttcheeks and the itchiness is driving me crazy. Is it really post-pregnancy hives/rashes or isit a side effect to the epidural. What do i do? Should i just wait it out Photos abit graphic but is worse at my butt area 😩 #pleasehelp #hives #rashes #postpartum
