Well my update I did call the vet and the vet tech who is a super nice girl around my age said if I was worried to bring her in when the vet got in. So I did and he looked at her and said she was fine and that b/c she is so small the bruises are more noticable. He made sure we had some pain meds left and said she should be fine in a few days. I really think b/c she has stitches on the outside she feels the ends poke her and she freaks out and tries to run from it or lick at it. I do feel a lot better now that the vet saw her and said she was ok though! Thank you for your caring words!
