It's actually pretty common for fissures to be missed on exam. They aren't always easily visualized from an external exam. It also really depends on the day you are examined, how deep the fissure is, how far inside it is located, how thorough the physician can be given the risk f causing more pain and damage to the fissure by stretching the area too much. Unfortunately, it doesn't mean they aren't there. If there is pain and/or bleeding, something is causing it.
