have you used any kind like 腰封? it causes less pain cos on my 2nd day after c-section, I used it in the hospital and it helped me to move a bit, at least less pain when i got up from bed..but when you sleep at night, better don't use it because it blocks the circulation too much and can cause water retention to your lower body......use only during day time..Dr said i can use 收腹褲 too and also can help to make the 'scar' looks better....just also don't wear it at night during sleep
