<s>[INST] I rain into something about 10 weeks ago and hit my right femur, near the ankle, really hard. The hit was directly to the bone. It hurt a great deal at the time. I now have a lump on my shin bone, about the size of a small egg. Sometimes my leg hurts at night but typically I continue with my regular lifestyle (which is not terribly strenuous as I have a desk job). I am a 57 year old white female. What is the lump? Why does it still hurt? Do I need to worry about it? [/INST] Hi, It can be a hematoma after the injury. It is nothing but a collection of blood underneath the skin after the trauma. Generally, it will settle by itself without treatment. You can apply ice packs and can take analgesics and anti-inflammatory combination for symptomatic relief. If symptoms persist, better to consult an orthopedic and get evaluated. Hope I have answered your query. Let me know if I can assist you further. </s>
