@eddiestella1 There is a lab that tests for immune responses to surgical implants in Chicago. They have you send in a warm blood sample. It may not be covered by insurance.

If you do have an allergy to a metal in your body, you could contact the Environmental Health Center in Texas. This is the practice of the doctor that created this medical specialty and it has been continued by the staff after his passing. They have treatments for these issues.

Surgical implants and metals in the body can cause pain. I experienced this after a bad ankle fracture and I had constant pain like being kicked in the shins. Eventually I had that hardware removed and I not longer have pain from it.

This post is from another member being treated for metal allergies from implants by this practice in Texas.
