 [ Symptoms ] i just had my 5th spinal fusion pain right now is all muscle related please advise [ Disease ] i am sorry about what you are going through you must feel very worried a forum like this is not the best place to get answers to your questions you need to rely on medical professionals infection is a potential complication of any joint replacement surgery it sounds like your surgeon is doing everything possible to determine if your joint is infected or not at this point it sounds like it is not the majority of orthopedic surgeons have dealt with the issue of post surgical infection if you are not satisfied with the answers you are getting from your surgeon tell him you want to be referred to someone else for a second opinion or perhaps he could refer you to an infectious disease specialist for a work up again i am sorry to hear you are dealing with these worrisome symptoms i hope everything gets resolved for you soon wishing you well
