I am currently treating my arms with the Fluorouracil (Efudex). This is the 3rd area of my body that I need to treat. I did a total of 11 treatments and had a major reaction very soon. My cream ran out and I missed 5 treatments before I got my refill and now in the healing phase. I'm not sure if I should start back with the treatments or if I need to let the area heal completely before I start again in order to get the full time recommended by my doctor?
