Hi doctor, On 14 September i fell from my scooty post to that i had Ankle injury when i visited to ortho specialist (i.e., on next day) he told me there is crack in bone so i was on cast. Cast was for 4 weeks n thn removed but i got no relief so i went another dr. He asked for MRI whichs shows following results Mild altered PDFS signal intensity noted in Kager's fat pad Possibility of bursitis. Complete tear of inferior band of anterior talofibular ligament noted. Mild edema noted in lateral malleolus in posterolateral aspect Possibility of  bone contusion. Marked subcutaneous edema noted in lateral aspect of ankle joint. Does this require surgery bcz it now more than one month i have no relief my foot is swelled like a balloon. Please advise.
