I'm new to this forum, and I know this thread's almost a year old…but I saw this and now know that I'm not alone. I was just recently diagnosed, as my symptoms have greatly worsened over the past 2 years. Long story short, I have often felt a tingling, crawling sensation coming from my anus. I was worried that I had a tape worm or something, although I seriously doubted the notion at the same time with my 8+bowel movements per day. I also thought that perhaps I had swallowed one of my wife's hairs, and like the dog's often do, had a hair hanging out or something. I didn't think to mention this to my Dr., but the colonoscopy confirmed, no tape worms atleast. I am about to start seeing a new Dr, and I will definitely be discussing all of my symptoms, regardless of if I think they are associated with my condition.
