<s>[INST] About 2 or even 3 weeks ago, I dropped something heavy directly on my foot. It was bruised for sometime but the bruise soon went away. At the moment, I feel no pain but I have a small bump on the inside of my foot, where the bruise used to be, should I be concerned? [/INST] Thanks for your question on Chat Doctor. I can understand your situation and problem. In my opinion, it is callus or million of fracture. You had foot injury 3 weeks ago. And after 3 weeks, you are having bump on trauma site. So possibility of fracture at the time of trauma and healing after 3 weeks is high. In bone fracture, healing occurs by callus formation. It is collection of inflammatory cells and calcium which give rise to appearance of swelling. Another possibility is million. If fractured fragments are not fused correctly then they can give rise to swelling due to million. So better to consult orthopedic doctor and get done clinical examination and x-ray of affected foot. </s>
