[|Human|] I crashed my lower leg into a metal beam about 4 weeks ago.  It hurt like heck, enough to be fractured,  but I ignored the injury and used my legs as I normally do.  A large, normally-flesh-colored lump about the size of a lemon remains, and is sore at times.  I assume it is a left over hematoma that will gradually dissipate.  Are there any concerns I should have about this? After how long should I be worried if it is not gone?
[|AI|]  Hi there. Looks like your injury is taking a long time to recover. I would suggest you keep an eye on for the swelling to increase in size or become suddenly painful. There are instances where an underlying tumor of the bone manifest after an episode of trauma. So you need to watch out for the same. If it is a hematoma with a fracture associated with it that is getting neglected, you will find difficulty in weight-bearing and walking on the affected leg, and you will need to get an x-ray of the involved region for the same and get treated appropriately.
