Many people with interstitial cystitis (IC) have problems with the group of muscles in the lower pelvic area and develop a condition called pelvic floor dysfunction (PFD). If you have IC and a poor urine stream, feel the need to push or bear down to urinate, and have painful intercourse, you may have PFD. Treating PFD may be very helpful in reducing symptoms and pain for some IC patients—most patients see improvement after several weeks of therapy.
Stop sucking in your gut. Sucking in your gut does not create core strength and can actually increase downward pressure on your pelvic floor. This creates a strain on the connective tissue in your abdomen by displacing your abdominal viscera. Many people hold in their bellies without knowing it. If you do this, try to consciously relax your belly while sitting, lying down, or in a cat/cow position on your hands and knees while taking deep, relaxing breaths. And pretend you are a dog or cat with your tail out—not tucked under you. Do this several times per day.
With her finger inside me, Christensen mentioned that the three superficial pelvic floor muscles on each side were very tight and tensed when she touched them. I was too tight and in pain for her to check the deepest muscle (the obturator internus). Finally, she checked to see if I could do a Kegel or relax the muscles, and I was unable to do either.
