My internist, my endo and my CDE (my endo's wife, both Type 1s themselves) all agree that it is probably an allergy. I can take a Benedryl and knock myself out, I can take a hydroxyz and the same thing happens, or I can take half a pill, which eases the itching but doesn't eliminate it entirely. I am, however, reluctant to add one more pill to my already-lengthy list. And it's been discussed with my medical team so much I expect they are all tired of hearing about it. And no matter what I do, my skin still looks awful--clumps of red around the edges of where the film was placed and some scabbing. Thanks for responding, though.
