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.
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 X-ray of involved ankle anteroposterior and lateral views to confirm diagnosis. Visit radiology center nearby you and get it done. If X-ray is showing changes of osteomyelitis you need to consult expert orthopedic 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 corroborates infection. All the best.
