Your problem may be from an infection like bacillary dysentery
. There are other problems like ulcerative colitis
or even a growth. If a stool examination shows amoeba or pus cells then a GP or internist can give you medicines to cure it. If the stool examination does not show these then I think you should see a gastroenterologist and get a colonoscopy
. This will probably show the cause of bleeding and then proper treatment can be taken.
Do let me know your progress.
