I can't say that exists. I will tell you what the stages of my sores were...first the were like knots under the skin(and painful) and some opened up and some did not...they oozed clear puss...then as I thought they were going the heck away as it had been at least 10 days and they were getting smaller, they turned into clusters of blisters that oozed like crazy and that's when the itching started. They still hurt like someone had hit me in my crotch but they itched something horrible too. It took over a month for the sores to finally go away but even now almost 2 months from my first outbreak, they still hurt(dull aching) but nothing is there?????!!!!! But there just isn't a way to tell you a natural progression of this virus as it's just so different from case to case. I do think that it is common for them to hurt at first and then itch later on. My BF only gets a little raw looking spot on his penis that pops up out of nowhere and then just goes away in about a little over a week. Some people only have itching like a yeast infection...some only burning during urination...I think that's the reason it's so hard for people to even know they have it. I think that people that are not familiar(people like me before I got it!) with herpes and haven't read up on it, assume it looks like ulcers all over your genitals but unfortunately it's not that obvious. Mine looked nothing like those hideous pictures on the internet...didn't look good but didn't look that hideous!
