@ferr Welcome to Mayo Clinic Connect. Yes, indeed, an infection can cause increased emptying of your bladder, as can changes in medications, presence of stones, or even diet. With your appointment on Friday, I hope some concerns get answered! Like @naturegirl5 mentioned, have you been able to recall when the symptoms started, and written down your thoughts? Sometimes when we get to the office, we forget important details, so taking a bit of time now might help you give all the information you want to pass on to your doctor.

Will you let me know what happens at the appointment, please?
