Hi there

I am going to first give you some information we have on our site about Efudex.

And here is the official Efudex site.  Here is what they say should happen in the weeks following:

"What will happen to my skin when I use EFUDEX®?

You will see the effect of EFUDEX® on your skin in 4 phases:

* Early inflammatory phase: During the first week of application, mild inflammation occurs

* Inflammatory phase: During following weeks, redness, and swelling occur with some crusting and burning

* Tumor disintegration phase: Lesions resolve as the skin exfoliates

* Healing phase: Over 1 to 2 weeks, new skin grows into the treatment area"

It may be just the healing process but if you have concerns...you should contact your doctor.

Hope you heal soon.  Thank you for your question.
