Obviously one can't know about the reaction until it happens. Not being
allergic to seafood at all, the reaction to the CT agent surprised me.
The nursing staff treated the swelling of my arm as an allergic reaction

Still don't know what was used; it isn't in my medical records. Took
three days for all the swelling to go away.
