Hello, You jumped off a swing and landed on the feet, you felt a sharp pain on your left foot but it went away. You now have a big bruise and two big lumps. It hurts you severely. You are suggested to give rest to your legs and foot and avoid walking. You can take the help of a walker or a walking stick so that you do not put your entire weight on the affected foot. Take NSAIDS, Combiflam or Naproxen, one SOS when pain. You can crepe bandage the affected part for relief. The crepe bandage should be such that it is comfortable (not tight as it will restrict blood supply and cause you more pain then relief). You are suggested to get clinically examined by an orthopedist and get X-ray done. If a fracture is detected you will be treated accordingly. Do not neglect as symptoms may go worse. Keep your affected foot elevated on a stool when you sit or on a pillow when on bed. Take care. Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. Nupur K., General & Family Physician
