I have reviewed your query and here is my advice. Swelling and pain in ankle common cause is ankle sprain.Have u twisted your ankle in near past? if yes ankle sprain is likely cause for pain. I would advise xray of involved ankle anteroposterior and lateral views to rule out bony abnormalities. you have to apply crepe bandage and keep your ankle elevated while not on duty. Tab trypsin chymotrypsin thrice a day  for 7 days helps in reducing swelling. Tab diclofenac sodium 50 mg twice a day helps in pain relief.Visit to orthopedic surgeon is recommended. Hope I have answered your query. Let me know if I can assist you further. </s>
