Thanks for your query,
You have not mentioned ,how many days back the event occured and whether the pain is decreased or increased. If it is bone (fracture
), then in those case there will be huge swelling and severe pain
. If the pain has decreased then it might be a organised haematoma
that will resolves slowly by itself. As you said it is still very painful, i think you may need some antibiotics to prevent infection in that area along with analgesics.
Hope i helped you..
