Brief Answer: Due to hematoma formation Detailed Answer: Hello, Thanks for posting your query. Severe pain with swelling and bruising with no detectable bone injury on MRI scan is likely to be due to a hematoma formation. Haematoma (internal bleeding) is usually caused by rupture of some blood vessel in the area. Usually these swelling are self limiting and will regress in a couple of days. You might notice change in its colour when it heals, from red to blue and finally pale to normal skin colour. Haematoma's are very painful. You can consult your family physician or orthopaedician and depending upon its size and severity they can decide to either excise it surgically or allow it to regress on its own. The only precaution that you must keep in mind is that it should not get infected (from any other source in body), cause if it does it will turn into an abscess. In my opinion, take hot fomentation with douche bag twice a day, take absolute bed rest, have anti inflammatory medicines with your physicians advice and supported walking till the pain and swelling subsides. I hope this answers your query. In case you have additional questions or doubts, you can forward them to me, and I shall be glad to help you out. Wishing you good health. Regards. Dr. Praveen Tayal.
