Ok so here's everything. I had sex 10 days ago(not last friday, but the one before that), with a close friend of mine, right after a little rough foreplay(fingering, and he used a vibrator on me, which was mine, and it was the first time using it). After the sex, I only felt the usual discomfort that I always feel, and then after that discomfort was gone by the next morning, everything was back to normal. He wanted to hookup again on Sunday(two days later), but I said I couldn't. So, he urged me to use my toy again, and just think of him, which I did. I tried using it with a fast deep motion once I got into it. I think I might have rubbed something I shouldn't have because I had this burning sensation afterwards that wouldn't leave, and a discharge that was light yellow in color, and more of a sugary smell too it. I was very swollen on the left side of my vagina lip, very close to the bottom. I thought I might have cut myself too, because it had a very bad burning sensation in that area when I went to pee(just as getting any type of liquid in a cut will burn). It's been 7 days now and the swelling has gone down a lot, and it still burns but not as much. Two nights ago I got the Monistat7 for a yeast infection, just hoping thats what it is, and have taken it the last two nights, and the night before I started to take it, it also started burning every time I went to pee, and I had too frequently. I have bacterial vaginosis that comes and goes, yeast infections that do too(not as common, but still common), and UTI that come and go also. I've had Strep B(a type of UTI) twice in my life,one of the times being 2wks ago but I don't think it could be that this time. I took a small hand mirror and checked, but there are no visible cuts anywhere. The left side of my lip in the swollen area, is starting to loose puffiness, but the redness is still there. I'm not sure what to do because I think the bacteria is inside(if bacteria is what's there). I'm not sure if I can put any type of cream on the area where my lip is swollen to either help remove the bacteria or burning sensation. A burning sensation also started today, even when im not peeing, and when I do pee it burns even more and gets really warm. PLEASE HELP! if you know of any remedies or creams please let me know!!
