Hi,
Abdominal cramps and long ribbon like stools could be due to irritable bowel syndrome. Fiber supplements along with probiotics, antispasmodics and antidepressants would provide relief.
If you are above 50 years of age, colonoscopy may be done.
Your heart attack like symptoms could be due to GERD. 24 hours pH monitoring test and upper GI endoscopy may be done for evaluation. Medications like omeprazole would be helpful.
