I think i have internal hemorrhoid but could be anal fissure. my stools clearly show "gouging" caused when passing through the rectum. suggestions?

Fissure is painful: Anal fissure is very painful mostly and internal hemorrhoids are painless on the contrary, a thorough evaluation by a physician preferably a colorectal surgeon is recommended to make sure no serious pathology is going in.

See your doctor: you could not make this kind of diagnosis based on the shape of the stool there is big difference between a fissure and internal hemorrhoid you might have both go and see your doctor or a colon rectal surgeon they can examined you and tell you exactly what is wrong good luck
