Burn cream

About 3 weeks ago I went to the dermatologist for my bi-yearly checkup.  He said that I still have a lot of pre-cancer on my face and had me do the 4 week cream treatment to burn off all the bad spots (why did I lay out in the sun so much when I was a teenager?)  Wednesday will be 3 weeks using the stuff and my face is red and burning.....and sometimes itching like crazy.  I have to use it for 4 weeks total and then let all the sores heal.  Every once in a while I'll get odd looks from people cuz it looks like I have road rash on my face.  Steve says that my face looks like I'm drunk.....what a goof!!  Fortunately, it should be cleared up by the time we get family pics.
