There are many different treatments that doctors recommend for patients with IC/PBS. Only a few research studies have been done to evaluate treatments given to patients. Treatment choices can be of two types: drug therapy and non-drug therapy. The two treatments used in this study will be of the non-drug therapy type. One of the treatments being used in this study is called Myofascial Tissue Manipulation. This is a kind of physical therapy that is designed to work on specific muscles and tissue layers in a particular part of the body. In this study, this treatment will focus on the areas around the pelvis and the pelvic floor. The treatment will involve the physical therapist's use of hands and fingers to target specific muscles and tissues located within your pelvis, rectum, and/or vagina (the pelvic floor) as well as muscles and layers of tissue in your abdomen and legs. The other treatment being used in this study is Global Therapeutic Massage. This treatment involves the physical therapist's use of classic Western body massage techniques on the muscles of your arms, legs, hands, neck, shoulders, back, stomach, buttocks, and feet to create an overall feeling of well being.
