Resubmit Q: You should not bruise after or because you donated blood or blood components--your body has more than enough cells to control leaks, and while you may bruise at an injection site (where needle was), it is not 'mandatory'--this is why the blood bank wraps the site and tells you to keep it on for at least 4 hours.
