I am a 24 year old male and I've had blood in my stool off and on for the past few months. It's a streak of blood that runs down one side of the stool. The blood is bright red and I also find it on the toilet paper after wiping. Is this a hemorroid or something else (anal fissure)? Is it a big cause for concern? I don't like going to the doctor, so I'm trying to avoid that. Otherwise, I'm perfectly healthy, never had any major health problems. I do have IBS and I tend to not drink much water or eat enough fiber. I have an anxiety disorder which probably doesn't help. I find that I have to strain alot of times when I'm going to the bathroom. Could straining cause a tear and could this be the cause of the bright red blood in my stool? Thanks in advance for any insights you can provide.
