The symptoms of a UTI is a strong urge to urinate that cannot be delayed which is followed by a sharp pain or burning sensation in the urethra when the urine is released.Most often very little urine is released and the urine that is released may be tinged with blood. The urge to urinate recurs quickly and soreness may occur in the lower abdomen,back,or sides.
This cycle may repeat itself frequently during the day or night--most people urinate about six times a day, when the need to urinate occurs more often a bladder infection should be suspected.
When bacteria enters the ureters and spread to the kidneys,symptoms such as back pain,chills,fever, nausea,and vomiting may occur,as well as the previous symptoms of lower urinary tract infection.
Since you've already had your appt,I would call the doctor's office and tell them that you had meant to have a UA but forgot and wondered if you could drop by to pick up a specimen cup so you can bring in an early morning specimen.
If you are prone to frequent UTI's,you may consider drinking more water(if you dont drink enough)and boosting your intake of Cranberry juice or juice..If you cant tolerate you can buy Cranberry pills..
