Hi everyone,I went to see my doctor yesterday because the pain of my left side was sometimes too much to cope with and he said that it was diverticulitis again and he gave me patches of Fentanyl. Is somebody familiar with this medication? After reading all the info, I realized that it was not the kind of medicine I needed. I'm not familiar with this medication but the side effects sounds really bad and the only thing I would like to know from my doctor is to check where the problem is. I started to have a little bit of fever everyday and the left side is swelling badly reaching the back and the pain is bad but not everyday. He also ordered an ovaries test to rule out cancer there and a stool test. I already had a colonoscopy and the specialist told me that he wasn't able to go too far because of a lot of spasmes and he suggested me to start smoking again.(that was when I quit smoking, 3 years ago), I got also a gallbladder and stomach checks and of course there was nothing wrong except diverticulitis in the bowel. Any suggestions? Thanks a lot in advance.
