Hi welcome to Health care magic forum.
Thanks for calling H.C.M.F.
You had abdominal pain
, associated with blood motions repeating often, and there is relief of pain in between the passing of blood.
It appears to be the amoebic dysentry
, or irritable bowel syndrome
but it must be a chronic happening since long time.
Your choice of consulting a gastro enterologist is correct, with the treatment with anaerobic antibiotics along with other drugs you will be all right.
Besides i advise you some diet recommendations as take bland foods, avoid taking spices, junk foods, and oily foods.
Wishing for a quick recovery.
