Two years ago, my gallbladder was removed. Almost two months after having my gallbladder removed, I suffered a rash on my chest, that looked like a sunburn, and burned and itched. Now, I suffer from a rash on my chest every two months or so. Prior to having gallbladder surgery, I never suffered from a rash on my chest. Could the titanium surgical clips be causing my rash? Could I be allergic to titanium/nickel? Thank you.
