Hello! Thanks for putting your query in HCM. I am a Gastroenterologist (DM).
Painful bleed per rectum is an alarming feature which requires investigation as soon as possible.
It may be inflammatory bowel disease
, some malignancy in colon, tuberculosis
of colon, acute dysentry
etc. So I will like to advise you to visit a Gastroenterologist who may advise you to undergo colonoscopy
I hope I have answered your query and this will help you. Remain in touch and get-well soon.
