Hi Dimples,
That's Awesome -- It is amazing how wonderful and different your outlook on life is without the constant pain. I, too, am highly allergic to nickel, but my surgeon gave me the option of what to do. Based on what he told me, what I had read, and what info I got from having my blood tested by Rush University for a research project that they are conducting on this very issue, the conclusion I came up with was that the evidence thus far did not support without a reasonable doubt that people with skin metal allergies are prone to an allergic reaction with deep tissue implants. And, I have not had any problem whatsoever with the implant and I am 17 weeks postop today, 5/20/08. Good decision on your part to go ahead with the implant even though you are allergic to nickel.
Good Luck and know that you are well on your way to a normal life again without pain
