I have had some of your conditions. I was diagnosed with a nickel allergy. It’s in most implants and the cement used to secure it. I was tested by a lab in Chicago. They sent the kit to do it. This only happened because I took the lead on this. My doctor told me I couldn’t be allergic. Skin test doesn’t work on everyone, you need a blood test. I went through 5 TKRs before I found out. Only 6 percent of males are allergic to some form of surgical metal in the US. Still living with the fact that my body has been poisoned with nickel for 3 years. It seems you are invested in your health, stay that way, doctors are not always right. They mean well, but don’t know everything. Trust what your body is telling you. Hope all goes well.
