I,too, have had this problem. I was told to take a stool softener. It is not a laxative, it just make the the stool slide through without roughing up the edges. This gives the lining a chance to heal without further damage. Maybe this would work for you. This was a few years ago, ocasionally I still have some bleeding, but not very often.
Seeing blood is scarry, but this is not a serious problem.
Best to you.
Colace is a stool softner. You also need to make sure you drink plenty of water and you might also try taking Metamucil or Citricel as well. I had a hemmrhoidectomy in February so I certainly know all about hemmrhoids. Any other questions you have please feel free to ask. You also need to be eating a high fiber diet, but most importantly is your water intake. Take care and best of luck to you.
