So glad I found this thread.
I got a small lump on my lip late last week. It was only slightly noticeable when not wearing make up, but once I'd got my lipstick on you couldn't see it at all. At the weekend, thinking it was just a spot (I'd not had any tingling or soreness), I tried to burst it, as it had a tiny head, then put some sudocrem on it. After a couple of days trying sudocrem and toothpaste, it wasn't drying out, and kept cracking open and weeping. It didn't even occur to me that it would be a cold sore as I've never had them before and not knowing what the symptoms were I was constantly picking at it. Lipstick covered it well up until this morning when I woke up, and saw that it was really sore, itchy and angry. I decided to nip over to the chemist. I told her what I'd done, and she said it probably was a spot, everyone carries the virus, it just lies dormant until something triggers it, and me trying to pop it and constantly touching it, has probably done just that.
. She suggested Aciclovir 5% cream, which is apparently the same as Zovirax, so hoping it goes away in a few days, and that I don't get another break out. However looking at this thread, the likelyhood of it been a one off seems pretty slim.
I'm praying like mad that I've not passed it on to my hubby over the weekend, and I've now had to message my bookings this week to tell them I've got a cold sore, and if they want to see me there will be no kissing or oral bothways, just massage or S&M. Totally gutted.
