Hi Kerrie. A Hematoma is like a bruise, but to a greater extent. Some of the blood, the body will absorb and get rid of (like with normal bruising), with hematoma there is a much larger collection of blood outside of the blood vessels, which in most cases (like yours) will have to be drained. I’m sorry it hasn’t been a good experience for you so far and hope you feel better and heal well 🙂 xx
