Allergy to metal in THR

[Guest guest]

At about 7 months post op for a THR my leg started swelling. My doctor

tested for a blood clot and infection; both negative. Two months later

I am still swollen with intermitent pain and nightly discomfort. After

a CTscan, my doctor said he thought I was hypersensitive/allergic to

the metal in my hip replacement and that I would most likely need

another surgery to replace the metal with plastic. Has anyone in this

group encountered this diagnosis before and if so, what action was

taken? Thank you for any information you can give to me.
