Welcome to JA. Anal pain during a BM is not caused by IBS but may be caused by a hemorrhoid. A hemorrhoid can also cause streaks of blood. The most common cause of this type of pain is an anal fissure. This often results from the presence of the hemorrhoid and is a tear in the anal mucosa. It will heal in time but will heal more quickly with the use of a prescription steroid cream. This can easily be diagnosed by physical exam by your regular Dr. You should have an exam and an accurate diagnosis before treating it.
If you are able to see the hemorrhoid externally it can be treated with Anusol or Preparation H over the counter as well as A and D ointment for comfort. Steroid cream that is over the counter can also be applied to an anal fissure. Stool softeners like docusate sodium, over the counter, are helpful during the healing process.
Nothing to do with IBD right? I know the difference between IBS and IBD but I read somewhere that IBD led to complications in the anus area. I am guessing IBD leads to more fistulas and strictures - not fissures - right?
