I have had similar swelling problems. About a year ago I got what I thought was a yeast infection with a swollen vulva so I went to the Ob/gyn. Before this I had never had swelling or anything like that with a yeast infection. I was swollen soooo bad it hurt to sit down, get up, walk, pretty much do anything. I was treated with the diflucan and given a cream to use for a week. About a month later it came back..swelling and everything, so I made another friendly doctors visit. This time it was a bacterial infection. I was treated with antibiotics and give this gel to use for 2 weeks. Each month thereafter was a repeat occurance of one or the other. One day, while on my monthly inconvenience, I was in the bathroom changing my pad and noticed some sort of fragrance as I was opening the pad. So when I got home, I checked the package and the same products I had been using for years added a new odorfighting agent. However it said nothing of fragrance on the package. Well I quit using them immediately...and bought Kotex unscented pads. The problem went away. I was sooo relieved having finally figured out the problem. Since then I haven't had as many infections but I do seem to get them more frequently since the "Pad incident of 2007" and ever since then my vulva on one side or the other swells. I went to the Ob/gyn today for what I thought was once again a yeast infection. She checked out my vulva and it was swollen...with what appeared to be almost like a pimple she told me. She said the pores down there can get clogged just like anywhere else...and that it's actually very common. So she squeezed the heck out of it and got most of the puss out (which as I'm sure you figured hurt like heck) and she told me I should get a shower and try to squeeze it again later. She did the swab and looked under the microscope and there was no yeast present but from the overuse of the products I now have no good bacteria present at all. She asked if I had been tested for Diabetes...which I had been, but it was in 2006. So one more test to take I guess. So I'm supposed to only use pads...which I've always done, and not wear any underwear, just loose fitting pants or shorts to bed to let things calm down. So basically I'm back to square one...A new and different reason for the swelling on any given day I guess. She told me that if I get another infection next month that I should just take the diflucan and not use any creams..so I can keep some of the good bacteria. She recommended a specialist if I keep having this problem. I hope that all of this goes away and I hope any of this at least makes someone feel better in the sense that they're not alone. I'm 25 and married and I never thought I could have these kinds of problems. Vulva wasn't even a word in my vocabulary until last year. I don't use fragranced anything...laundry detergent, dryer sheets, body wash, deodorant, feminine products, perfumes, lotions...nothing. I eat yogurt every day, and drink cranberry juice. Good luck to all of you. I hope your problems go away.
