I had this very same thing happen.. less the dogs and scared hubby! I laid down in bed the 3rd night, still slightly propped up and my internal stitches pulled. My stomach area felt like it was caving in! Weird. My daughter helped me back to the chair and there I stayed for 12 nights! I am a belly sleeper and I am just now, 1 month out on 1-26, to sleep 1/2 side and belly. Hang in there!
