실험적: Arm 2 Experimental Arm (n=70)
Intervention Name: Venlafaxine + Education and Behavioral Modification Program (EBMP) Intervention Description: Full identical EBMP intervention as control group, plus flexible-dose oral venlafaxine for 12 weeks.

Dose down-titration allowed for intolerable adverse events to identify individual maximum tolerated dose (MTD), maintained until week12 endpoint.
No rescue analgesic, NSAID or other antidepressant allowed during study period.
Weekly telephone follow-up to record drug compliance and adverse reactions.

Mean Visual Analog Scale (VAS) Bladder Pain Score
기간: Baseline, Week 1, Week2, Week6, Week12
|
0-10 Likert scale; higher scores represent more severe bladder/pelvic discomfort.
|
Baseline, Week 1, Week2, Week6, Week12
|
|
Pelvic Pain and Urgency/Frequency (PUF) Total Score
기간: Baseline, Week 1, Week2, Week6, Week12
|
8-item scale total score ranging 0-40; higher scores indicate worse pelvic pain and lower urinary tract symptoms.
|
Baseline, Week 1, Week2, Week6, Week12

O'Leary-Sant ICSI + ICPI Composite Symptom Score
기간: Baseline, Week 1, Week2, Week6, Week12
|
ICSI (0-20) evaluates frequency, nocturia, urgency and pain; ICPI (0-16) measures symptom-related life interference.
