Build a useful symptom timeline.
A short factual log can reveal repetition. It should describe what happened, not attempt to decide why.

Start with time and duration
Note when a change starts, how long it lasts, whether it wakes you at night, and whether it is becoming more or less frequent. Dates are often more useful than general statements such as “it happens a lot”.
Describe the change plainly
- Where is the discomfort?
- Does passing urine feel different?
- Is there urgency, hesitation or a weaker stream?
- Is discomfort linked with ejaculation?
- Are fever, chills or blood present?
Add context, not conclusions
It can be useful to note long sitting periods, fluid timing, alcohol or caffeine, unusual exercise, constipation, poor sleep and high-stress days. These observations can help a conversation, but they do not prove a cause.
Bring the log, then let the appointment do its job
Take the timeline, a medication list and your main questions. If symptoms are persistent or worsening, arranging an assessment is more useful than extending the journal indefinitely.
