Bowel Disorder :: Bright Red Blood With BM

I'm new here but from what I've read I'm probably far from the first person to post about this. I'm just looking for other peoples advice/experience to help calm my nerves.

About me, I am male and 25 yo average weight/height.

For the past few months I've been having some bowel problems. Starting around October last year I began having on and off issues with some slight indigestion and small amounts of bright red blood when I had a BM. These issues would come and go. I had a small issue similar to this in 2014 and had a colonoscopy performed to check. The test didn't find anything out of the ordinary. In November of last year I had a Flexible Sigmoidoscopy performed due to the recent issues. This test came back saying that I had internal hemorrhoids but nothing else. I didn't do much to treat them and just sort of hoped they'd go away.

The mild issues continued until about late January/early February when I was hit with a week long bout of indigestion, excess gas etc. As these issues continued the bleeding ramped up until I was seeing bright red blood staining the toilet bowel each time I had a BM. It didn't seem like an immense amount of blood but it was enough to tint the water and toilet paper red. Due to these issues I went back to GI doctor around the second week of February. He did an examination with his hand and noted that I had internal hemmies and slight inflammation. He pointed this out as the most likely cause of the bleeding given the results of my previous tests. He recommended I start taking Konsyl fiber supplement and Preparation H suppositories.

After starting with the suppositories the indigestion and excess gas went away as well as the excess blood. My usual BM schedule resumed (1/day). Since then however I still see small streaks of what looks like bright red blood with each BM. Some days are not as bad as others but it seems like there is always a small amount of blood there. I've also had an intense itching sensation down there that would come and go every once in a while. Like I said before for the last 2 months I've been going at the same rate and the stool consistency is normal. I don't seem to have any excessive pain or weight loss.
My main question is for anyone who has had hemorrhoids. Can bleeding last this long? One thing I've noticed is that I seem to have fairly large/hard stools which I think may be causing trouble. I wouldn't call it constipation exactly just that the stools are large/dry and often require some light straining to expel. I also work a desk job and have a 2 hour daily driving commute. I've recently bought a seat cushion for my chair and car with hopes that it will help.

I'm sorry for the wall of text. I want to get past this but I am an extremely anxious person and this bleed issue is ruining me. I'm scheduled for a follow up with my GI in 2 weeks and am getting the sinking feeling that I'm in for another colonoscopy.

P.S. I've also had an abdomen CT scan in early 2015 due to a separate issue. No problems were found.
