I had diarrhoea 2 weeks ago, for the whole week along with stomach pains indicating that i needed to "go". Last week there was no sign of diarrhoea. My diarrhoea started acting up again yesterday after i ate taco bell. Now (today) i have severe stomach pains and the urge to go, but i am not able to go. I am also very gassy. It seems that about an hour or so after i eat a meal i start to feel sick and feel the need to go.
HI Thanks for posting your query.  It seems like you are having Indigestion due to eating of Taco Bell. You need to avoid very oily food and non veg food for at least 10 days.  Also eat more of Citrus fruits which accelerate the digestion and give relief from your symptoms.  If symptoms persists ask your doctor for a prescription of digestive enzymes like Aristotle and use it, you will be alright. Hope this information was useful to you.  Any clarification feel free to ask.
