I had a cervical fusion at three levels on 5/13/13 and since then have had severe itching and rash across my neck, arms and feet. The surgeon used titanium with plastic, metal discs and bovine collagen. He states he has never had anyone allergic to the implants. I saw an Allergist today who is looking into the possibility and will probably do a MELISA test on me later this week. Nothing else has changed as far as soaps, food, bedding, etc since my surgery. What is the likelihood this could be caused by the implants?
