What happens if a hematoma is left untreated?

Leaving a hematoma untreated can lead to severe complications like infection, nerve damage, tissue death, and even life-threatening pressure on the brain or organs, potentially causing paralysis, permanent dysfunction, or death, especially with deeper or intracranial hematomas. While small, superficial ones might resolve, larger or deep hematomas can cause significant pain, swelling, blood clots, and compromise blood flow, requiring medical intervention like drainage or surgery.
