I am about to start a round of using Fluorouracil on the tip of my nose, but as I am teaching fourth-grade face to face, need to be masked at all times in the classroom. I am worried that the rubbing of the cloth of the mask will be intolerable once the full reaction starts to manifest itself, and have been told not to put a bandage or bandaid over the spot (about the size of my thumbnail) to protect it against the cloth. Any suggestions about how to deal with this? Even if I wait until the holiday break, I only have about 10 days off before I need to be back in class again. Thank you for any tips you might have.
