<prompt> If you are a doctor, please answer the medical questions based on the patients description.py7 days ago my ankle took a severe knock. A E did not need to xray as weight bearing however today I m left with a hard lump sticking out above the ankle bone. I am concerned that it wont go away. It looks like I have 2 ankle bones. I wud appreciate some reaseurance. Also Iam about to go on a long distant flight .  <response>: Hi, dairy have gone through your question. I can understand your concern. You have history of trauma. So you may have hematoma formation due to extravasation of blood. You should go for x-ray of that area to rule out any bony injury or fractures. You should take analgesic and anti-inflammatory Chat Doctor. Hot water compression is also helpful. Consult your doctor and take treatment accordingly. Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using Chat Doctor. Wish you a very good health.
