Pain on r low abdomen and worse during sex. acid reflux daily and bouts of diarrhea constipation nausea. had diarrhea saturday and stopped up since ?

Diagnosis: The internet is not the place for a medical evaluation that requires a full detailed history, a physical exam and then labs and imaging studies determined necessary by the first two elements. You really need to be seen and examined by a competent physician ASAP. Good luck and best wishes.

Complicated : With so many symptoms going on, you'd be best served by seeing a healthcare provider in person for a detailed history and examination.

IBS: Sounds like you have irritable bowel syndrome, possibly with GERD as well. Zantac (ranitidine) or Prilosec over the counter may help reflux/GERD. Would recommend high fiber diet and see gastroenterologist for further recommendations.
