I'm having a rough time 3 months after using Fluorouracil on my upper arms. I've had basal cell skin cáncers and then a squamous cell skin cáncer and my doctor prescribed Fluorouracil. It's been horrible. My arms still look like raw hamburger 3 months later. And I have horrible scars from the shave biopsies. I have bright red inflamed wrinkles. My arms are a mess. Has anyone else experienced this and will it ever improve?
