Hi, many thanks for the query!
Bright red blood in stools in your case seems to be due to the Piles that is "internal Haemorrhoides" which is painless unlike external haemorrhoides or anal fissure
which are painful conditions.
P/R Examination & Proctoscopy should be done by your general surgeon
to confirm the diagnosis.
Do blood examination for Haemoglobin
You can take anti-spasmodics for pain in abdomen.
Appropriate management of the internal haemorrhoides as per their degree should be done by a general surgeon, once diagnosis is confirmed.
Take high-fibre diet, green leafy vegetables, plenty of oral fluids.
Avoid bakery products, eggs, substances causing constipation
Wish you a good health. Take care.
