[|Human|] My husband had hip revision surgery in March and did good up until the second week of June. He is experiencing pain upon walking now but the pain is in different places, not always the same pain from day to day. He has been back to the doctor twice since June 19th and the last time the doctor drew out 50cc s of blood from the incision site, old dark blood. There is no sign of infection. He experienced some relief for a day but the pain has returned. Could this be a large hematoma after this much time has passed? There is no bruising but he does have swelling. He also takes Plavix and an aspirin daily..
[|AI|]  Hello, I have studied your case. PET scan will be useful now to establish the nature of pathology. There can be bursitis after the total hip replacement surgery, I suggest you to consult another Orthopedic surgeon (preferably a Joint replacement surgeon who has not done your surgery) for a detailed examination, workup and further management depending upon the nature of pathology. Hope this answers your query. If you have additional questions or follow-up queries then please do not hesitate in writing to us. I will be happy to answer your queries. Wishing you good health. Take care.
