Is any of this happening?
Be seen today
Seek prompt medical advice if you have visible blood in your urine, repeated urinary infections, fever with urinary symptoms, or pain in your side or back.
These symptoms do not always indicate a serious problem, but they need investigation.

Does any of this apply?
Book an appointment
Arrange a routine appointment if leakage is new, persistent, worsening, or interfering with sleep or daily activities.
You should also seek assessment for a weak stream, frequent urgency, repeated nighttime urination, pain when urinating, or a feeling that your bladder does not empty.
Every sign above is quoted from the sofidex article on Incontinence in men. If you are not sure, err upward — it is always reasonable to be checked.
