Brief Summary
The goal of this study is to compare the effectiveness of two different medications used in intravaginal trigger point injections (injections into extremely painful areas of a muscle) to treat chronic pelvic pain. The study compares onabotulinumtoxinA (BOTOX®) (a drug prepared from the bacterial toxin botulin which temporarily paralyzes muscles) to Kenalog (a synthetic corticosteroid used as an anti-inflammatory agent).

Outcome Measures
Primary Outcomes (4)
Pain Assessed by Change in Overall Pain Score Using the Visual Analog Scale (VAS).
The visual analog scale asks subjects to rate their level of pain on a scale from 0-10, with 0 being 'No pain' and 10 being 'Worst pain imaginable', hence lower scores are better. The baseline and follow-up visual analog scale for pain was obtained at every visit regardless if the patient received Trigger Point Injections. The difference between visual analog scale at 1 month and the visual analog scale at baseline was calculated. Positive numbers indicate the pain increased from baseline to 1 month and negative numbers indicates that pain decreased.
Baseline and One Month
Pain Severity Assessed by Change in Overall Pain and Other Related Scores Using Questions 3, 4, 5, and 6 in the Brief Pain Inventory (BPI) Questionnaire.
Pain severity was constructed by averaging questions 3,4,5 and 6 of the brief pain inventory questionnaire (adding scores together and dividing by 4). Each question is on a scale from 0 (no pain) to 10 (pain as bad as you can imagine). Thus, lower numbers represent a better outcome. The difference between pain severity at 1 month and the pain severity at baseline was calculated. Positive numbers indicate the pain severity increased from baseline to 1 month and negative numbers indicates that the severity of the pain decreased.
Baseline and One Month
Pain Interference Assessed by Change in Overall Pain and Other Related Scores Using Questions 9A Through 9G in the Brief Pain Inventory (BPI) Questionnaire.
The Pain Interference score was constructed by averaging the individual interference question scores from the brief pain inventory questionnaire (adding scores from questions 9A-9G and dividing by 7). The questions assess how, during the past 24 hours, pain has interfered with general anxiety (9A), mood (9B), walking ability (9C), normal work (9D), relations with other people (9E), sleep (9F), and enjoyment of life (9G). Each question is scored on a scale from 0 (does not interfere) to 10 (completely interferes). Thus, a lower value represents a better outcome. The difference between pain interference at 1 month and the pain interference at baseline was calculated. Positive numbers indicate the pain severity increased from baseline to 1 month and negative numbers indicates that the severity of the pain decreased.
Baseline and One Month
Pain Assessed by Change in Overall Pain Symptom Using Question 2 of the Global Response Assessment (GRA) Questionnaire.
The GRA questionnaire asks subjects to rate symptoms and functioning since having the research procedure, Trigger Point Injections (TPI). Question 2 asks the subject to rate their pain symptoms since having TPI. Scores are on a Likert scale, ranging from 1 (Markedly Worse) to 7 (Markedly Improved).

Study Arms (2)
Onabotulinumtoxin A
EXPERIMENTALIntervention is a one time 30 cc intravaginal injection totaling a dose of 200u of onabotulinumtoxin A and saline injected throughout the pelvic floor at 1, 3, 5, 7, 9 and 11 o'clock sites/locations. An injection of 30 cc of ropivicaine (5cc/6 sites) will be used, followed by a mixture of 200 u of Onabotulinumtoxin A and 6 cc of saline (1cc/injection site).
Kenalog
ACTIVE COMPARATORIntervention is a one time 30 cc intravaginal injection totaling a dose of 40mg/cc of Kenalog (triamcinolone) and ropivicaine 0.5% (29cc) injected throughout the pelvic floor at 1, 3, 5, 7, 9 and 11 o'clock sites/locations. A mixture of 40mg/1 cc of triamcinolone (40 mg) and 29cc of ropivicaine 0.5% (5cc/6 sites) will be used, followed by 6 cc of saline (1cc/injection site).
Interventions
Intravaginal pelvic floor injection one series

- Patients that have had Botox outside the bladder of \> 160 u within the last 12 weeks.
- Patients that have had transvaginal trigger point injections of any form (Botox or steroid) in the last 3 months
- Pregnancy
- Concomitant use of any narcotic drug, alcohol, or any illicit drug use during the study period that could be deemed unsafe in combination with study medication as judged by the investigators.
- Any evidence of vaginitis on wet mount slide at initial visit that is untreated.
- Subject with any other vaginal epithelial disorder that could affect absorption of medication as deemed by the investigators.
- Any indication/condition/medication that the investigators identify as contraindicated in conjunction with study medication.
- Systolic blood pressure \> 160 mm Hg on screening blood pressure
- Heart rate \> 110 beats/minute on screening heart rate
