Ugh, this is so embarrassing. But I need some insight. A few years ago I got my first fever blister/cold sore. Since then, I've had 1 or 2 and that's it. And every time it was always the exact same spot. A week ago, I got the first one in a different spot literally out of nowhere (right before missed period) and then today (a week later) the first one is healed and I have a SECOND one that literally JUST appeared in a different spot. My question is, can hormones cause cold sores/ fever blisters to be frequent?! It's been well over a year since my last one! 😩😭😩😭
