Household hint for today: If you've got a cast or some sort of surgical dressing that needs to be waterproofed whenever you bathe, wrap it in Glad Press'n Seal. It sticks to itself and to the skin, and doesn't need as much tape to hold it in place.
I learned this tip from a nurse at the Ambulatory Treatment Infusion Center (acronymically called, of course, "the attic") when I was describing how hard it was to wrap a plastic bag around my left arm with my right hand in order to cover my PICC line. They had given me one of those plastic sleeve thingies that are usually used to cover casts, but it also covered my left hand, meaning I couldn't use it to wash with.
So I got a roll of Press'n Seal (why they can't call it, more correctly, "Press 'n' Seal" I don't know) and sure enough, it does the trick.
What a strange little world of expediencies I have found myself in.
