<s>[INST] I fell on my knee 10 days ago and it swelled up quite a bit. I can walk fine, but cant put any pressure on it. The whole lower half of my leg turned black. I went to the doctor and he took xrays and said it was fine. He said that I had a contusion in the knee that was seeping down the leg. I don t know if I landed on my ankle or not but it is swollen and bruised to the point that my whole foot doesn t have any definition anymore.... it is very very painful. Is this normal? [/INST] Hello, I have studied your case and I think that you have developed ecchymosis in the leg with swelling and due to this you are having pain and discoloration. I would recommend you to follow these steps.1. Hot water fomentation2. Compression bandage and tablet Govern if pain is there .3. Rest4. If ecchymosis increases then you need to check your blood coagulation profile as some time this can also cause increase bleeding tendency and such symptoms. I hope this answer will be helpful for you. Let me know if there is any other followup questions. Thanks </s>
