<human>: My boyfriend hit his shin bone very hard on a trailer hitch four days ago. There was a goose egg and now most of that is gone but there s a lot of swelling and pain. This morning a strange bruise and more swelling appeared about 5 inches below the injury. He says he s in a lot of pain.
<bot>: Hi, Pain may be sudden and severe. Bruising and swelling may develop soon after the injury. Acute injuries usually require prompt medical evaluation and may include: Bruises (contusions), which occur when small blood vessels under the skin tear or rupture, often from a twist, bump, or fall. He needs to evaluate for fracture. He limb should be mobilized and should be kept elevated to prevent from further swelling. The more swelling the more pain may occur. Hope I have answered your query. Let me know if I can assist you further.
