Sue, thank you for responding. I am being evaluated by two ortho docs, both with different approaches. Have had pain and dysfunction since the original surgery which makes it hard to know when the metal issue started. I wonder if lower levels of toxicity over a dozen years could do damage. The two surgeons I am consulting are very good doctors. However, I wonder if I should be finding a revision specialist with expertise in metal issues? I have had exrays, blood work and mars mri, with a repeat scheduled since it’s been a year. One doc may order a CT scan. The other says he’ll find out what’s wrong when he goes in. I would not return to the original surgeon.
