I very well could have bumped into something and can’t recall but there’s a huge purple bruise that’s been on the back of my thigh for about 5 days. Doesn’t hurt. I don’t remember hitting myself. But I was running around packing for vacation (and could have knocked into something) about 5 days ago and noticed it while I was away. I do know bruises that appear out of nowhere and don’t go away are bad bad news!! Has anyone gotten anxious over this?
