Hi all. I've come across this site and hope I'm ok to post. I have tiny patch of AK on my ear at the top next to the fold. It's about 4mm. Was prescribed efudex 1 x daily for 21 days. At day 14 and the only thing happening is it's getting lighter in colour and smaller. None of the things the dr said - burning, pus etc. It feels a bit tight and maybe a little dry. Is this usual?
