Suggest Treatment For Chronic Bowel Irritation And Interstitial Cystitis

I have suffered with bladder and bowel problems for the last 12 years. I was diagnosed with chronic intersistial cystitis,then they decided it wasn t,then I had to do self catheterisation because they thought I had urine retention,then they decided I didn t. I have also been told I may have irritable bowel. However any medication I have taken has not helped anything at all. I also have mouth and sinus problems. I feel I have a nightmare going on inside my body,but no one is listening.
