Girls, who used a bandaging for pregnant women when experiencing back pain? I can't even walk from the word. At home I can do chores all day on my feet, but as soon as I go out of the house, my belly immediately tightens and it becomes very difficult to walk. By evening, there is pain in the back, I walk around the house a bit and it gets better. There is no spasm! I often go for ultrasounds. I will have a cesarean section and I want to know if they used this same bandage after CS or bought another one?
