Suggest Treatment For Severe Interstitial Cystitis

I have severe interstitial cystitis and I am currently under treatment for that; however, I complained of a constant sharp pain above my umbilical cord (pinching and stabbing pain) and feeling nauseous whenever the bladder pain is bad. My urologist checked for hernia but did not see any. I continue with the pain, but now I feel bloated, my stomach hurt and I have more frequent bowel movements. I don t have diarrhea, but my feces had blood on them and when I wipe I see a brown, foul smelly mucous. Now I am naseous most of the time. I thought it could be a gastroenteritis due to the medicines I take for the cystitis(antibiotics, pain and anti inflammatory pills and for the vomiting), and I have been giving it time to go away by watching my diet, but It s been a week already. What do you recommend me to do? Thanks for your advise and information.
