5-fluorouracil & calcipotriol for actinic keratosis

My doctor has prescribed a combination 5-fluorouracil and calcipotriol topically for solar actinic keratoses on my face. Has anyone undergone this regimen? Is it as bad as it appears to be on Dr. Google? Does the treatment work? What have you is most useful to reduce pain? Are cold compresses or acetaminophen allowed or helpful? Tips for keeping the cream from getting in your eyes? How close to the hairline and onto neck do you apply it? Long-term is your skin more sensitive? Has anyone used low-level light therapy (LED) to promote healing after completing the regime? Any insight or tips you can share would be greatly appreciated. I’m so very apprehensive.
