Bruises, First Aid 

If internal bleeding is suspected, there is bleeding that cannot be stopped by self-care measures, or if there is serious trauma (eg, a potential spinal cord injury), seek emergency medical care. If bruises appear for no apparent reason, particularly if you don't have a previous history of bruising; if there is a loss of function (eg, you suspect a broken bone); if you are bleeding elsewhere (particularly from the gums or nose, or you notice blood in stool or urine); or if bruises are large and particularly painful, seek medical attention.
