Brief summary:
This study is done to investigate the pain relieving effects of the study drug Gralise (a novel long acting gabapentinoid) for people who experience chronic pelvic pain. Subjects with Irritable Bowel Syndrome, Interstitial Cystitis, Ulcerative Colitis, and Prostatitis will be recruited. The purpose of this research is to look at how the study drug can be used to benefit people who experience this type of pain. This is a phase IV study done to study the safety and effectiveness of the drug. At this point the drug has been approved by the Food and Drug Administration and has been reported to be well tolerated and effective in the treatment of various chronic pain conditions, particularly in neuropathic pain. About 36 subjects will take part in this study.

Detailed description:
As a participant in this study, you will be asked to come to the Rehabilitation Institute of Chicago (RIC), Center for Pain Studies (446 E Ontario St. Suite 1011, Chicago, IL 60611). Your part in this study will last for 15 weeks and will involve 4 visits to the Rehabilitation Institute of Chicago and anywhere from weekly phone calls to phone calls every other day.

If you are in this study, you will be placed in one of two study groups: one group will receive the study drug followed by a placebo and the second group will receive a placebo followed by the study drug. The amount of weeks on placebo versus the study drug will not be equal. You will be assigned a study group by chance using a process similar to the flip of a coin. This process is called randomization. Neither you nor the study staff will select the group you will be in. However, if you have a medical emergency, we can get this information. A placebo looks like the study drug but is an inactive substance that has no medication. Researchers use a placebo to see if the study drug works better or is safer than not taking anything.

Arms:
arm 1: Subjects may receive a pill with no medicine (placebo) for phase 1. Subject washout, then cross over to Gralise in Phase 2. arm 2: Subjects recieve Gralise (a long acting gabapentinoid) for phase 1.Subject washout, then cross over to placebo in Phase 2.

Interventions: intervention 1: Gralise
Intervention descriptions: intervention 1: Subjects will start at 600mg and titrate up by 600mg a week for two weeks (to 1800mg), then remain on 1800mg steady state dose of medication (or placebo pills) for 2 weeks. If intolerable side effects occur, the dose may be reduced to last tolerable dose at the discretion of the PI. A 2-week down-titration will be used. Subjects will have 1 week of "wash-out" before repeating the above procedure for the other arm of the study (placebo or medication).
