Call Orthopedic Analysis in Chicago, after my TKR 2019, I was stiff and in pain and my Ortho said i may be allergic to metals, when I asked him about allergies, pre-surgery, he brushed it off and I trusted him (big mistake). I had 8 vials sent to OA and found out I'm highly allergic to nickel and mildly allergic to chromium, cobalt, iron & bone cement. I'm living with it, a ticking time bomb but don't want to redo until i have to. I had my other knee done 2022 with Smith Nephew, zirconium but had to use bone cement. I'm 67, used to do Ironman's, now I can hardly walk, but ok, both knees are stiff but I ride my assist bike everyday and walk a little. I think your general Doctor could order the test. Good luck!!!
