Hi welcome to Health care magic forum.
Thanks for calling H.C.M.Forum.
Your husband had Pain in the right lower abdomen, radiating towards the center, usually starts after eating the food, get worse during the period,
nausea, there is bloody
diarrhoea, this is all since 3 years.
It appears that he had inflammation of the descending colon,
rectum, may be due to
ulcerative colitis,
irritable bowel syndrome,amoebiosis, there may be associated
urinary tract infection.
I advise you to consult a surgeon for diagnosis and treatment. You may need to have M.R.I.
colonoscopy, besides other routine tests for confirmation.
I also advise him to avoid spicy foods, junk foods, and oily foods. advise to take more of water, and curd.
Wishing for a quick and complete recovery.
Best regards.
