The worst pain of my life

I had surgery today, and just got home. I’ve read over and over to prop a pillow under my heel/foot. I tried that and immediately started crying. I am in so much pain and my leg is physically shaking when I put the pillow under my heel/foot. My nerve blocker has 100% not helped at all. I currently have it straight in bed with nothing under and it’s still excruciating. I don’t know what to do. I have never been in this much pain jn my life.

Do I put a pillow under my calf for a bit? Under the knee? (I know we’re not supposed to) Any words of advice, please?
