Urinary tract infections (UTIs) commonly cause a strong, persistent urge to urinate, a burning sensation during urination, and passing small amounts of urine frequently. Urine may appear cloudy, dark, bloody, or have a strong odor. Lower abdominal or pelvic pain is common, especially in women, while men may experience rectal discomfort. Fever, chills, nausea, or flank pain can indicate a more serious kidney infection. In severe or complicated cases, especially in hospital settings, treatments may involve injectable antibiotics; information about ceftriaxone injection wholesale is often relevant for healthcare supply discussions rather than patient self-care.
