@april0608 The type of implant and all components are part of your surgical record. Every piece is identifiable by a serial number, and both the doctor and hospital will have this information, as wee as the type of cement (if any) or fixation hardware such as screws.
I don't think what you are seeing is metallosis in the usual sense, which as defined as excess chromium and cobalt ions in the blood. Metal on metal hip implants have not been used for a number of years. The diagnostic tool for metallosis is a blood test for those metals.
But, you could have sensitivity to one or more of the metals in your implant. (titanium, nickel and I believe chromium are still used - just not in such a way as they rub against one another and cause shedding of ions.) If you did not have a cementless implant, it is possible to be sensitive to the bone cement used. The way these are tested is different. All components used must be identified, then sensitivity tests (usually skin pricks) are performed to check for reactions.

Do you know which hip implant you received?
