@Afraser, my point exactly.....it's not that they were used, it's that I was not told that they were used and will remain there. Titanium appears to be a safe option, that the older version had nickle as well, which caused problems in some. However, there is a small population of patients who can, in fact have an allergy to titanium, specifically those with autoimmune problems which put them at risk of their bodies over reacting to what, in others, would be seen as no threat by their bodies. That is, an inert substance not worthy of getting excited about. In my case, by body goes apeshit over essentially nothing, as a matter of course. I have scleroderma, Sjogren's Syndrome,and antiphospholipid antigen syndrome, as well as positive antibodies to lupus. All autoimmune diseases. I just feel that a heads up would have been appropriate, so that if at some point in the future, I manifested signs of some sort of allergy or whatever, it would have been on my radar that the clips might potentially be a cause.
