Spanky Thanks for asking. Today is Tues Feb 12 and 16 days after ending 28 days of 5-FU 2/d on both arms and hands. Again, the skin on the arms is MUCH different than face/scalp, but my arms "exploded" and I am very relieved to say that just today they are finally calming down.
I actually saw my dermo this morning and he was impressed at the erosion extent, but said that all is good and many AKs should be eliminated and potential future cancers reduced greatly. As Jef and others suggest, my doc also said a light coating of bacitracin followed by Aquaphor in the morning after showering was the best protocol during healing - after TX. 5-FU is very strong and everyone has different reactions. Some have serious side effects, so consult your doc if at all concerned. Hang in there.
