What causes ankle pain and swelling?
Patient: I have pain in my left leg starting at the ankle. The pain is especially there at night. I had ankle surgery 7 years ago on the ankle. I still have screws in the footy. The pain seems to originate where the screws are located. Could I have developed a blood clot there? there is a continuous swelling. Doctor: Dear patient Past history of surgery on ankle with implant  in situ and pain now may be due to recent infection or screw breakage.  Since swelling is also there infection is  more likely.  I would like to advise Xray  of involved ankle anteroposterior  and lateral views  to confirm diagnosis. Visit radiology center nearby you and get it done. If Xray is showing changes of osteomyelitis you need to consult expert orthopaedic surgeon nearby you and get yourself examined. Complete  blood counts also needs to be done and of  there is  increased total leukocyte count it also corroborate infection. All the best..
