What Can Be Wrong With Me???

:cry: hello everyone my name is jessica and i'm 17 years old. My whole life I had uti's and kidney problems. Lately in the past 2 years I have had so new problems happen that my doctors wont help me solve. For over 8 months I had an ongoing uti that the doctors would give me medication but it would not work...If it did it only worked for a short time until I got off the medication and the uti would come right back. I just now got off a medication of bactrim (sry if I spelt it wrong) for over 7 months. I believe my lovely good old uti is now coming back. Before I was put on this presicription when I would take cultures they would come up pos. For a uti but some days neg. Even know I had one (we know this because I went to the doctors some times 3 times a week) they did some testing and said no that I did not have the following things:yeast invection, scaring or kidneys, enlarged kidneys, aids, or any sexual transmited diesase. Can someone help me figure out maybe what is wrong. We gave up on my doctors because they would never call us back, wouldnt answer our questions, wouldnt give me my test results, made us wait for over 2 hours when we had an appointment, and would not give me a doctor but gave us a college student and which they told me it was in my head and I was making it up. :evil: and so everyone who reads this know yes i'm in the process of getting a new doctor! Maybe someone can help me if they had a case like mine or is a doctor or has some knowledge of something. If you would want to know more about my case i'll be happy to post more thank you and please help me.
