Before treating bruising, check for other injuries such as a fracture. Bruising that occurs apparently spontaneously can be a sign of several different conditions. Consult a physician immediately. The bruise should eventually disappear of its own accord. Usually, bruises are red at first before turning blue, then brown, and finally yellow, as the blood is gradually reabsorbed.
Blood blisters are another form of bruising.
They display the same sequence of coloration, generally more vividly. Bruising that occurs some days after an injury near a bone may indicate a fracture. A physician should be consulted if this is a possibility, because if a broken bone is left untreated, it may cause severe complications in the future. Bruising in the abdominal region may be a sign of internal injury. A black eye is another form of a severe bruise.
