Yesterday and today I had this issue when I stretched up on my toes to hug someone so my belly was kinda tight and stretched and I heard and felt an audible pop. It was loud enough someone else heard and the person I was hugging actually felt it against their belly! Has this happened to anyone else? What the heck is it? Also I should mention it looks fine, I see no changes. Just freaked me out. I am terrified to mess up the muscle repair.
