You mention about having difficulty with bowel movements periodically.
If you are constipated and have hard stool and strain during defication.
it is possible to have hemorrhoids or fissure from which you can bleed.
With fissure or tear in the lining of the very end of rectum, you get
severe burning sensation. If you have internal hemorrhoids
, they can
prolapse or protrude after straining and you could feel a lump.
If you don't have these and are having bright red blood , you need
to see a colorectal surgeon or a gastroenterologist to have endoscopy,
or colonoscopy to rule out ulcerative colitis
or bleeding polyps. If you have a family history of colon cancer , you need
to have colonoscopy for sure.
The other problem associated with right lower abdominal pain
is acute diverticulitis
or bleeding from diverticulosis
, pockets from the colon
due to infection. Usually there may be fever , chills, bloody dirrhea and right
sided abdominal pain.
Hope this gives you some idea for what to discuss with your own doctor.
I wish you well.
