Hi my name is Jennifer I was taking a bath and had my leg up while sitting down and had this thing slide out between the middle of my ribs exactly where they meet. It was like the size 2 inch I guess it didn't hurt nor did I feel anything really but I thought it was going to stop my heart so I quickly touched it and kind of pushed it down and it slid right back kind of freaky... I have no health issues, but just want to know what it is...
