You had arthroscopic knee surgery last week how do know what is normal or abnormal bruising?

I am sure you have had a bruise on your body in the past, a black or blue mark that fades to green or yellow before fading altogether. Abnormal bruising is just that, abnormal, bruises that do not behave like normal bruises: black or blue marks that follow veins (infection), bruises so painful that movement is hindered, bruises that have something solid in them, bruises that get larger, bruises of non-bruise colors (red, white), etc.
