Currently there is no surefire way to distinguish PFD from IC, and oftentimes patients have both conditions. Some healthcare providers examine pelvic floor muscles externally and internally to gauge their tightness (tightness indicates PFD). Other IC and PFD experts, like ICA Medical Advisory Board member, Robert Moldwin, MD, perform a lidocaine challenge. By instilling lidocaine into the bladder, Dr. Moldwin determines whether your pain is coming from your bladder, which would indicate IC.

Pelvic floor dysfunction is common for many women and includes symptoms that can affect all aspects of everyday life and activities. Pelvic floor muscle (PFM) training is vital for treating different types of pelvic floor dysfunction. Two common problems are uterine prolapse and urinary incontinence both of which stem from muscle weakness. Without the ability to control PFM, pelvic floor training cannot be done successfully. Being able to control PFM is vital for a well functioning pelvic floor. Through vaginal palpation exams and the use of biofeedback the tightening, lifting, and squeezing actions of these muscles can be determined. In addition, abdominal muscle training has been shown to improve pelvic floor muscle function.[12] By increasing abdominal muscle strength and control, a person may have an easier time activating the pelvic floor muscles in sync with the abdominal muscles. Many physiotherapists are specially trained to address the muscles weaknesses associated with pelvic floor dysfunction and through intervention can effectively treat this.[13]
Biofeedback uses electrodes placed on your body (on the perineum and/or the area around the anus) or probes inserted in the vagina or rectum to sense the degree of tenseness in your pelvic floor muscles. Results displayed on a computer or other device provide cues to help you learn to relax those muscles. Usually, patients feel relief after six to eight weeks of therapy. You may be able to buy or rent a unit to use at home.
Medications: Daily medications that help to keep your bowel movements soft and regular are a very important part of treating pelvic floor dysfunction. Some of these medications are available over-the-counter at the drugstore and include stool softeners such as MiraLAX®, Colace®, Senna or generic stool softeners. Your primary care doctor or a gastroenterologist can help to advise you which medications are most helpful in keeping your stools soft.
Kegels: American gynecologist Arnold Kegel created this seminal pelvic floor exercise. To do a Kegel, contract your muscles that stop the flow of urine, hold for five seconds, then release for five seconds. Repeat this exercise 10–15 times, up to three times per day. Avoid doing Kegel exercises when urinating since stopping the flow midstream can cause some urine to remain in your bladder, putting you at a higher risk of urinary tract infections (UTIs).
