Is any of this happening?
Be seen today
Seek prompt medical advice if you have visible blood in your urine, pain when urinating, fever, repeated urinary infections, or new leakage after an injury or procedure.

Does any of this apply?
Book an appointment
Arrange a routine medical appointment if leakage is new, persistent, or affecting sleep or daily activities.
Assessment is also appropriate if you have a weak stream, difficulty starting, frequent nighttime urination, or a feeling that your bladder does not empty.
The article also says
New bladder or bowel changes with leg weakness or numbness around the groin can indicate pressure on the nerves at the base of the spine.
Every sign above is quoted from the sofidex article on Urinary incontinence in men. If you are not sure, err upward — it is always reasonable to be checked.
