On the night of day 4, I had so much itching that it woke me up, to the point that I felt I was having some kind of "reaction". I took Benadryl and was able to go back to sleep. Until this point, everything has gone very smoothly. I had Fraxel 3 years ago, so I'm not new to this kind of treatment. But today, I'm still itching, and it came after 2 days of heavy flaking. Is this normal? What can I do about it?
