Hello, i am a 30 year old woman. no medical concerns that require medication or treatment (that i am aware of) For the past 3 days i have been suffering from severe stomache pain and diarrhea. within 60 minutes after i eat anything, be it fruit, sandwhiches, meat, vegetables, cereal, etc. you name it. 60 minutes afterwards i am on the toilet for roughly 30 - 40 minutes with intense painful diarrhea, and before that severe stomache pain, afterwards i have stomache pain as well. i am scared to eat anything... what could this be?
