you are presenting with irritable bowel syndrome
and probably due to poor digestion. So you could take an antispasmodic like spasfon (phloroglucinol) for the cramps and associate with digestive regulator like debridat. Also review your diet in last 24hours and see what you ate that was not normal. Also note that location of the cramps on specific regions/quadrants of the stomach can also help us differentiate a nephritic colic
from an abdominal colic.
Wish you a quick recovery
