I was constipated for a while, and when i had too go there would be blood in stool. now those symptoms just magically dissappered how often is that?

Constipation blood: Constipation and trying to force your stools by pushing can sometime call abrasion in the anus and that will cause the bleeding when you go and strain again, sometimes internal hemorroids will bleed when you are constipated.If your stools are normal now that might be a reason why it stopped.Since you did have blood in the stool, it is a good idea to see a GI specialist and have colonoscopy done aswe.
