With normal urine tests, scans, and a clear gynae exam, this sounds more like a sensitive nerve or pelvic floor pattern than an infection. Health anxiety can genuinely make you notice and worsen these sensations too.
Next Steps
A pelvic floor physiotherapist can assess whether tight or irritated pelvic muscles are behind this, since your worked-up causes have come back clear.
Health Tips
If you ever notice blood in urine, fever, or new pain, get it checked again rather than assuming it is the same pattern.
