Weird Feeling in my Belly

[BK_Adores_Chase]

So I can barely touch my toes - part of my daily workout routine is stretching, and when I sit down, legs flat on the ground straight in front of me I wrap my hands around my head and pull down gently so I'm looking at the ground and it gives me this horrible feeling, mainly in my stomach.  Why?!  Am I stretching my spinal cord - it's such a gross feeling.
