<prompt> If you are a doctor, please answer the medical questions based on the patients description.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?  <response>: 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.
