I found sleeping with the V pillow really hurt my back.. think its because there’s no support in the middle so your back is left under pressure.. felt a lot better when I put some softer pillows behind my back with a hot water bottle and sometimes a pillow under my bum to straighten me out a bit. I was sleeping flat by 4 days post op and when my nurse from mya rang to see if I was okay and how I was getting on, she said it was fine 🙂 xx
