Cystitis. When you have a bladder infection (cystitis) you can have symptoms of lower abdominal/suprapubic pain and/or pressure, as well as low back discomfort. You may or may not also have foul smelling urine, the frequent need to urinate, cloudy or bloody urine. Might want to see your doctor and have a urinalysis performed to rule out an infection. .
