I'm a pretty healthy 22 year old but for the past few years off and on I have experienced, painful burning in the vagina and urinary tract. I was treated for a yeast infection several times and it did not go away. I was treated for Trichomoniasis and it didn't go away and I have also been treated for vaginitis and UTI's and a few weeks ago they thought I could have kidney stones because my urine culture came with blood and puss in it but they did another culture a few days later and it came back normal. I'm hopeless right now, I don't know what to do, I'm tired of going to Doctor after Doctor to receive no help, they act like my symptoms don't exist or aren't as severe as I say they are. I have been with the same guy for the past 5 years and neither of us sleep around. Because of my problem(s) I can't have sex and I'm afraid that it may hinder me from having children one day. If anyone can offer some advice I would be thankful this is really taking it's toll on me. Oh I also sometimes have a flanking pain in the left lower side of my stomach.
