Which symptom is typical of a lower urinary tract infection?

Explanation:
Lower urinary tract infections involve the bladder and urethra, so irritation of the bladder mucosa leads to symptoms centered on voiding. The most characteristic sign is increased frequency of urination, as the bladder irritability makes you feel the need to void more often. Fever and nausea point more toward upper urinary tract involvement (like the kidneys) or a systemic infection, rather than a simple bladder infection, and headache is nonspecific. So frequency best reflects bladder irritation from a lower urinary tract infection, with other typical bladder symptoms including urgency, dysuria, and nocturia.
