I am 20 years old and suffer from urinary tract infections since I was 13 that I can remember. After an antibiotic session they would return within a months time. Regardless of weather I had what I thought was an infection at the time or not I would always test high for white blood cells in my urine. I have never had a kidney infection though. I have practiced all the techniques for preventing one for years and years and that doesn't seem to help. I have had the same UTI for about 6 months now and I am pregnant. My first doctors appointment is on Nov 18th, so Im sure something will be done. i just haven't gone to the doctor because its frustrating when nothing helps. I have symptoms such as burning in my urethra while and up to 45 minutes after I urinate. While I have this burning pain I have painful bladder contractions that makes it feel like Im still urinating. I don't know whats going on but no doctor has tried to find the underlying cause, just treats the symptoms. Also, I had a staph infection when I was 2 years old that almost killed me, it ate through almost all the skin on my back, could that have done something to my immune system? I also used to be prone to getting bronchitis and pneumonia from ages 6-8. I've also already had my appendix removed and had IBS before I chnaged my diet. The doctor who treated me almost thought I had chrones disease. Well that's not all but I am cutting it short.
