Bruises occur when small blood vessels under the skin tear or rupture, most often from a twist, bump, or fall. Blood leaks into tissues under the skin and causes a black-and-blue spot that often turns colours, including purplish black, reddish blue, or yellowish green, as the bruise heals.
Bruises hurt, but most are not serious and will go away on their own within 2 to 4 weeks. Sometimes, gravity causes them to spread down the body. A leg bruise usually will take longer to heal than a bruise on the face or arms.
Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse call line if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.
