There is no excuse for what the nurse did. She/he should have carefully lifted the edges of the dressing with a small alcohol wipe & gently eased the Tegaderm off. It's possible you had a skin reaction to the drsg. itself, which caused the redness. Do you have a Latex allergy? Aquaphor is a good healing ointment (OTC) that might help it heal more quickly. I hope you feel better soon. Take care.
