I just had back surgery a week ago. I was allergic to the tape from the dressing and i think the steri-strips caused some breaking out also. But now I am itching really bad all over. My cheeks, around my nose, and chin is really red, warm to touch, bumpy, and very itchy. Can you give me some ideas of what maybe going on? I have taken Benadryl and used Benadryl cream. It's not helping.
