[|Human|] hello, i banged my left leg close enough to the shin a couple months back now and since it happened theres been a lump, for the first week or two there was bruising and sensitivity to touch that went around the 1st 2nd week but this lump has remained.
[|AI|]  Thanks for your question on Chat Doctor. I can understand your concern. Since you are having history of trauma on tibial bone, possibility of hematoma or callus formation is high. Any bone injury heals by either callus formation or hematoma formation. And it appears as rounded lump like swelling. So better to get done ultrasound examination of local part. If it is hematoma or callus then no need to worry. It will resolve by its own slowly. Hope I have solved your query. Wish you good health. Thanks.
