Things are progressing well now, as is the pain.
I find its at it's worst in the morning as you start moving your face/forehead muscles. It's like having ground glass rubbed into an open wound. I'd gladly advocate having Botox done before doing Efudex... but I admit that having this stuff on my forehead means I don't move it around as much.
As the day goes on, it gets better painwise, and I find that some of the redness tames down a bit.
I'm SO glad I started doing this in the fall and not at the beginning of summer. Even sitting in sunlight through the car window is very painful.
I started putting the Efudex on the rest of my face and ears two days ago, and I'm off to the Drs. tomorrow.
