Hello After childbirth, my whole body itches - arms, legs, belly, face, even in my nose and ears. I thought my skin was dry and cracking, so I started taking care of it, after washing every time I slather on cream or oil, but it still itches. Then I thought maybe from bed bugs, but my husband didn't itch, so I still disinfected the whole room, changed the mattress, but the itching didn't go away. What else could it be? Something hormonal? I'm done with it ?
