Hello and welcome to HCM
In my opinion you need to consult your gestro doctor immediately. You might be suffering from infection of intestine and colon or may be Heamorriods or Fissure. To be examined and confirmed by proctoscopy examination. If this examination is negative than you may need colonoscopy
to check any lesion or site of bleeding. In the mean while do stool for occult blood, Liver
function test and Heamogram.
In diet take high fiber diet, Hard diet (which is not digested easily) and take plenty of water. Rest depends on the diagnosis. Consult your doctor and get proper treatment.
