Keratosis
"I was on Fluorouracil two times a day for two weeks. It wasn&#039;t too bad for the first 10 days then it continued to burn more with every application.  

The most painful part of the Fluorouracil treatment was after I completed the applications. A nurse recommended that I mix %u2153 cup of white vinegar with 6 cups of water and place the mixture in the refrigerator until chilled. Then, use a very soft wash cloth and the vinegar solution to cleanse my face.  She also said to take the damp wash cloth and place it over my face for 15 minutes 4 times daily. 

Contrary to what I thought, the vinegar solution did not burn, it soothed incredibly."
