After 5 weeks of Efudex twice a day and about another 3-4 weeks to heal, I was so very happy to have a healed, pain-free bottom lip. Sadly, within a month, the AK lesions returned. Next week I meet the plastic surgeon for a consult on the referral for a Vermilionectomy. Pretty anxious about that process but would be nice to eat, drink, brush my teeth without the stinging pain. Love to hear from anyone that has gone through this procedure.
