Metal allergies cause inflation and lack of healing.
Get a blood test which tests all the components of the appliance, hardware, implant and bone cement.
Speaking from personal experience I have accepted my knee disabilites rather suffer with allergies to the implant.
I do have multiple contact allergies, not counting all my environmental allergies so I am always aware of my contacts.
My knee surgery was scheduled and I requested a test for all the elements before the surgery date, yet even with my orthopedist writing up my allergic medical history Medicare wouldn't pay for this test. I paid $600.00, blood was taken and sent to lab in Chicago which tested for various metals and also the bone cement.
I learned I am allegic to 5 metals, however titanium the main metal used in the implant did not test positive. However the othopedist explained there is no such thing as pure titanium. It contains traces of other metals, including the ones I was allergic to. In time the implant erodes from wear and not only the titanium is released into your body and bloodstream but these trace metals are too. Not only would the locatized area react but also these trace metals could be release thoughout your body and stored as heavy metals are. He did explain a ceramic coated implant could be used, but in time the ceramic coating thins and metals are exposed.
If eddiestella1 is still following this post I hope blood testing is considered and if positive removal of the implant/applicance is considered.
Your orthopedist should be aware of a lab that provides this test but if not I have the address of the lab in Chicago, Il that does this testing and I will get out my records and post it.
This will sound cynical, but I personally believe doctors, just like the orthopedist group I went to, don't suggest allergy testing of the components, not because of the personal expense to the patient which Medicare will not pay for, but because at least 5 % of their sugeries would be cancelled. You may be part of the 5% like me.
