I get a bit of blood in my stools or on toilet paper sometimes, not everytime. It's not very much and it's bright red. I'm 20 years old. I assumed it was piles but got referred to check it out. The doctor said he couldn't see piles or anything so he's referred me for this flexible sigmoidoscopy which is basically a colonscopy of the lower bowel. I'm worried though that my health anxiety may have blown this way out of proportion. I'm worried this procedure will be more dangerous than my actual problem. I'm not sure just reading about the procedure has frightened me and I don't want there to be any risks. Do you reckon the blood could be attributed to very small piles that the doctor couldn't really see?
