- Blood vessels are routinely injured and may leak blood causing hematomas or blood clots.
- Depending upon their size and location, hematomas may be insignificant or may cause life-threatening damage.
- People who take blood thinners like warfarin (Coumadin) and clopidogrel (Plavix) are at higher risk of bleeding from minor injuries.
- Most hematomas resolve by themselves and need no further treatment, but some may require surgical treatment.
- Injuries to the head should be taken seriously because of the risk of bleeding causing injuries like epidural, subdural and intracerebral hemorrhage.
