Possible UTI: The typical symptoms of a UTI (bladder infection) are urinary urgency, frequency, voiding small amounts, burning, and bladder pressure/discomfort. Typical symptoms of a vaginitis are vaginal burning, itching, discharge, redness usually not associated with any significant change(s) in urination. I would suggest you contact your md for either a urinalysis, urine culture, and/or an antibiotic rx.

Sounds like a UTI: It sounds like the beginning of a urinary tract infection. I would recommend making an appointment with your primary and discussing the need for treatment, possibly with antibiotics. If you start getting very sick, don't be shy about going to er.
