"At 65yo and lifetime in the sun and numerous treatments including surgery, cryotherapy etc Doctor said will have to use Efudix to whole face as had untold AK's plus Bowens Disease. Told it was a ''brutal'' treatment. He was right.
All I can say is that this treatment was the most painfull experience in my life. By week two I was in agony but forced myself to continue the three week treatment. A word of warning. Under no circumstances get this stuff on your genitals. I did and it was agonising. Pain so intense sent me into depression for 3 months. Results were excellent however and no regrets."
