Welcome, rdb, I had
Erbitux last October, and the rash started my 2nd dose, and lasted for a few weeks after completion, but not on my face as much, but lingered on top of my head, arms, legs. I felt an itch ball with the dry skin too. Did they give you Minocycline 500mg 3x a day? I took a few days, and my light rash on the face went away, which looked funny cause it was right on the tip of my nose lol. After that was gone, I stopped taking the meds, which I probably should not have.
Seems to be a reduction of treatment theses days with
HPV positive in the oropharynx. I had 70Gy my first time.
Good luck with your PET scan.
