I am a 31 yr old female. I have constantly been having UTI like symptoms for the past year. Urinalysis shows I only have WBCs in my urine and no nitrates. I've had a cystoscopy, CT scan, and various other tests and all come back normal. All cultures come back normal. What else could this be? What other tests should I be asking for? I've seen 2 seperate urologists and no resolution. Other symptoms I have are low blood pressure, hypoglycemia, fatigue, occasional dizziness/nausea, anxiety, sleep problems, craving of salt and sweets, and irritability. Thank you for any help you can give me.
