Sweetlady, welcome to my world. I've been plagued by cold sores since I was five years old but they only came a few times a year. Once I started the MTX, which as you probably know suppresses the immune system, I started getting them every day on my face, mostly my chin and lower cheek area and sometimes the lips. I take a prescription called acyclovir for it and it helps a lot, but I don't want to be on yet another drug for the rest of my life so the RD switched me to Imuran. Now I'm on both but will stop the MTX when the Imuran kicks in. Are you on any drugs that are suppressing your immune system? That's what usually makes herpes eruptions worse.
