I also have keratosis all over, arms, legs, hands, chest. I am on day 24 of my first round, whcih is my chest and shoulders. Wehn I am done there I plan to do my upper arm, then my lower arms, and then the tops of my thighs. I have been doing my hands with my chest/shoulders. My hands are not showing much if any reastion, but my chest and shoulders are seriously on fire. Like the rest, I can't sleep, and every movement I make start the burning all over again.
But I will keep up with it, because the AKs were getting so numerous and ugly. I am 41 and have tried the laser lights, freezing, etc. This is actually my second chest treatment, I quit the first time (five years ago) after 7 days because of the pain. But I will stick it out this time.
