I get my outbreaks on the butt cheeks. This is the reason I didn't know I had HSV2 -- pimples on butt cheeks are so common. It's pretty difficult for me, too, because of that. I never know if I'm getting an outbreak or if I just have a normal zit. I get nervous at every little red bump. I've tried to solve this problem by using an exfoliating cream (to limit the ingrown hairs that could make me panic!). At least I have a nice soft butt now! But seriously, if anyone else has the same OB location, I"d love to know your experiences. I've heard about "tingling" but I don't seem to get any tingling whatsoever to warn me something's coming. I've had what I think is tingling on the lip (I also have HSV1), that feels sort of like fizzy water on the edge of my lip, without OBs (I've only had a cold sore once), but I've never felt anything similar below the waist. I've only known I had this since my third OB, and so may not be recognizing the prodromes, but it seems like the OB just appears out of nowhere, and I only notice it because it itches. By that time it's already a red welt, like a big mosquito bite. I vaguely remember having lower backache once, but can't remember if it was pre-OB or not. Now and then I've had pains in the back of the thighs, but again, can't remember when with regard to the OB. Anyone have prodromes that I might be missing? I'd like to be able to see them coming. Please tell me how it happens for you.
