Well, Christine, I was never as bad as you describe so this might not apply to you. I tried the proctofoam and it was very small device and certainly did not go far into my anus or rectum. Then I tried the enemas and they were too difficult for me. Well, if I remember right (yikes, getting old) when I got the Cortifoam - I said "the container has a lot bigger tube to insert - goes further up. It is working for me. I always lay on my left side for 1/2 hour at least.
Good luck and sorry you are going through this. I hate to type this because of jinxing or something but I have not seen any blood or mucous for weeks (months) - just having diarrhea once in while but you know having IBS that happens. I use the Anusol or Cortifoam when I feel somewhat irritated hopefully to stop the inflammation before it gets out of control.
I believe you are getting our snow - up here in the snowbelt we have had a mild winter.
