Can bladder infection cause you to feel nausea and stomach ache with back ache.? er put me on bactrim (sulfamethoxazole and trimethoprim)

See below: Classical symptoms for a bladder infection (cystitis): burning with urination, bladder discomfort, urinary urgency and frequency. Blood in urine, incontinence, lower abdominal and low back discomfort may also occur. If UTI involves kidney (pyelonephritis): fever, chills, nausea, vomiting, mid-back/flank pain, feel sicker. Bactrim (sulfamethoxazole and trimethoprim) good initial choice for either. Kidney stone can mimic UTI symptoms.
