Ligaments of big toe was crushed. This?

Hi, Mayank name is Mayank. I was feeling little pain while playing badminton in my big toe ball or joint but One day when I woke up, I had a severe pain in my toe ball and I could stand on the foot due to heavy swelling and pain. So I visited to doctor and he did the x ray and uric acid test. Then x ray was ok and acid was 3.6. Then he told me that your big toe joint ligaments have been crushed while playing. So it will take time to heal and gave me medicine for swelling & pain and a steroid pill i think [ named Deflazacort] and one was multi vitamin. After taking it these medications for 1 month and 10 days. Now i can stand in my foot and there is no pain and swelling. So pain killer is stopped. But Now I can feel like a cyst while walking just in the place of toe ball. While in other foot I feel nothing. It's like something round shaped flash is above my toe ball or it the toe ball that is swell and I fee it while walking. I do not know how can I treat this? Please help Thanks
