vaginapagina | Weird Rash and Swollen Glands

Hi all,

I'm having some really bizarre symptoms, and I can't get to my gyno till Friday, so I thought I'd see if any of you have any idea what this is. About a week ago I got this REALLY painful rash on my thigh right where it connects to my crotch. I figured it was just razor burn or heat rash or something and ignored it. But yesterday I woke up and the same rash is ALL over the top of my vulva and now on the other side of my leg. And the lymph nodes around my crotch are really, painfully swollen.

I'm certain that it's not poison ivy, and I haven't been bitten by anything recently that I know of. I also just got std-tested, so I'm fairly certain that's not it as well, though I know that's always a possibility. Also, I'm having some bladder issues. I don't know if they're related or not, but thought I'd post about them just incase they might be. It doesn't really feel like I have a bladder infection (I've had PLENTY before, so I know what they feel like), but when I need to pee, it's hard to do. Like, when I squeeze my bladder muscles I then have to unsqueeze them and sort of wait a few seconds for the pee to come out. Graphic and weird, I know, but I'm desperate here. I've convinced myself that I'm going to drop dead of some horrible disease before my doctor's appointment so I need whatever info you guys have. Anyone ever have anything like this happen?
