Hi Tracy, I've always had a slightly flatter lower back arch. I found it actually became more normal after I'd been doing pilates for a while. Regardless, it's extremely uncomfortable, at times painful, for me to lie flat on my back. It's better if I bend my knees, but who can sleep like that for any length of time.

Good luck today.

Hugs,

Kat
