?Where: Most hematomas spontaneously resolve in time (gone within 3-5 weeks). On a rare occasion some hematomas are walled off and may need surgical removal. (hematomas in different areas, for example a more serious sdh (sub dural hematoma) needs to be cared for emergently as it can cause pressure on the brain, etc.) hope that helps answer your question.
