Tina - I'm not a doctor either, but pretty sure that's not how our bodies work. The metal, in order to be found in our bloodwork, must be disseminated in the tissue and working its way into the bloodstream. It is then eliminated as bodily waste.
Was your blood retested after revision surgery? That is how to tell if there is any metallosis remaining.
The symptoms you are experiencing now are concerning. If you believe your revised hip is failing (pain or inability to move your leg) please see your ortho.
Otherwise, this sounds quite alarming enough to warrant a call to your primary provider.
