Girls, I can't wear the bandage alone? It annoys me especially when I have to put it on lying down, it's not comfortable for me at all. I'll always dress it wrong, or it's too loose, or vice versa, it's too tight and I end up freaking out and take it off... Tell me, is it really necessary to wear it lying down? The doctor says it's definitely necessary, but it's just so uncomfortable... I'm already tired today, I tried to put it on four times in total and ended up taking it off, I'm worried about what will happen next, they said it's definitely necessary to wear it.
